The Genesis of A Game About Snowmen

0 Comments | This entry was posted on Apr 14 2016 by

David Rosen of Wolfire Games game a talk at GDC 2014 about procedural animation in Overgrowth (available here). I found his talk fascinating on two levels. First, it was quite interesting how he was able to get so much from so little. Totally fluid animation from just a few keyframes and a little bit of math for intelligent interpolation. Second, he made it look easy enough that I could do it, even with my extremely limited art skills.

By the time this made its way to the top of my to-do list, it was late in 2014, and snow was on the ground. Snowmen seemed like the perfect opportunity to learn about procedural animation, while at the same time allowing me to stretch (and squash, lol) a bit beyond what the video covered, applying the techniques in a new way.
Lookin' Good

It worked out pretty well. The next step was to build a game around this neat animation.

Two Utopias – A game about diversity

If you haven’t yet played Two Utopias, please do so now by clicking here. It will only take about 60 seconds.

Two Utopias is a game about diversity. More specifically, it’s a game about the conversation about diversity. Each of the two utopias, A and B, represents the perfect society imagined by one side of the discussion. Communicating through a game transmits feelings as well as thoughts, as each player can experience living in a representation of each utopia, rather than having to imagine it. This sort of communication is also demonstrated in Lazy 8 Studios’ A Game about *, which I strongly recommend. Playing that game led directly to the creation of this one.

In utopia A, everyone just acts ‘normal’, and moves steadily towards their goal. Because everyone conforms to the accepted standard of behavior, there’s very little conflict, and it’s easy to fit in and succeed. There’s more to the story, however. Just because it’s easy to fit in doesn’t mean it’s fun, or even bearable. It is impossible to break out of your assigned place in the society of Utopia A without causing conflict, and to fit in, you have to handicap yourself, slowing down to the collective pace of the group. Waiting for everyone else to catch up can be both frustrating and boring.

In utopia B, each person follows their own path and desires, and those desires can be dramatically different from yours. Sometimes, this makes your goal very easy to achieve, as everyone else generally stays out of the way, pursuing their own goals. Other times, it can seem impossible to make progress toward your goal, as there is always someone in the way. Additionally, while the people in utopia B never get into conflict with each other, they go to amazing lengths to accomplish that feat. They do things to avoid conflict that you simply can’t, and you can find yourself in a situation where conflict is inevitable. Even if you try to avoid conflict, with so many different sorts of people, it can be impossible, even if you abandon your own goals completely and focus only on conflict avoidance.

Two Utopias isn’t trying to send a specific message as much as it’s trying to help people evaluate and think about their own beliefs and goals. There are as many different messages as there are people with different points of view that approach it. If there is a common theme, it is that neither A nor B is a true utopia, where everyone is happy and productive. More thought should be given to the sort of world we are trying to create when we advocate change, beyond simply opposing behaviors and situations we find unpleasant. Only with a clear goal in mind can any goal be achieved, and only with a truly utopian goal can the support necessary for real change be gathered.

…and it only took four days. It’s a massively multiplayer online implementation on Conway’s Game of Life. The game is played on a grid laid over the Earth, and players can only color the square they are physically in. Each grid square is approximately eleven miles across and the cycle time is ten minutes, so it will take teamwork to make interesting structures. I’ve seeded the world with some random noise, so that if you manage to get four friends and make a glider, it will have something to interact with. Check it out at

Inspiration not all that inspiring…

Inspiration, the game I had hoped would prove a worthy successor to Influence, is dead. It is definitely deceased. It is not resting, stunned, or pining for the fjords.

What happened was this: I had the idea at MineCon to make a thematic prequel to Influence, in which one would experience the formation of a great idea. I put together a demo showing off the mechanics I had in mind to illustrate this process in January of this year. The mechanics seemed fun, and all that was left was to design some compelling levels. Unfortunately, that’s where the wheels came off. It would be hubris to assume that nobody could successfully design fun levels out of the mechanics I put together, but I certainly can’t. I can be certain because I tried quite a few times, and all the levels were either boring of frustrating. It was impossible to hit the fun-and-challenging sweet spot.

Refining design by throwing out what doesn’t work is a key principle at Blanket Fort Games, and in this case, what doesn’t work is Inspiration. I have posted here the final demo, showing that my best shot at a complex level (the third in the posted demo), despite being intricate and requiring thought, isn’t fun.

Global Game Jam

0 Comments | This entry was posted on Jan 30 2012 by

This weekend was the Global Game Jam, where people all over the world made games in 48 hours which fit a common theme. Previous years’ themes have been words or short phrases, but this year they took a different approach. This year’s theme was an image, specifically, the Ouroboros. They say a picture is worth a thousand words, and it’s true. The Ouroboros is an ancient symbol from the dawn of civilization, and therefore has many connotations and uses. It is found in alchemy, fiction, and several religions with all sorts of meanings. The Ouroboros can inspire a much wider variety of ideas than a single word like last year’s theme ‘Extinction.’ In my game, Roll, I used the theme twice. In Roll, you play a snake that’s biting its own tail, and you must roll down a hill five times. After the first roll, there is an opponent to defeat. The behavior of the opponent is the second use of the theme, but the specifics are left as an exercise for the player.

Influence Design Postmortem

0 Comments | This entry was posted on Dec 02 2011 by

When preparing the postmortem for Influence, we chose to focus on the design decisions, rather than the production details, for two reasons. First, we felt it would be more interesting, that audiences would care more about why we added or cut specific features than that we bickered for weeks over the names of the game modes. Second, we felt it would be more useful. Hopefully, everyone already knows that good time management is important, but they may not pay as much attention to their design process, or may not have looked at it in the way we now look at ours.

To view the slide show presentation of this postmortem, including new videos from the early development versions of Influence, as seen in the MineCon Indie Developer Theater, go to

What Went Right


One of the features of Influence we are most pleased with is the music. The design of the music went through a number of iterations, each improving on the last. Our first effort to make the game not silent was to put a popping sound in whenever an id was overtaken. The pops succeeded at making noise, but were unrelated to anything else in the game.

Our next iteration replaced the pops with steady tones. Each color was assigned a frequency around which their tone was based. The tone’s volume was bumped whenever an id was overtaken, so there was still an audible clue signaling game events, but the tones also reflected the state of the game. Louder tones indicated that the associated color controlled more ids, so players could tell if they were winning based on the sounds in the game. The tones were an improvement over the pops, but they still felt out of place.

Our final musical design iteration has each color represented by an instrument. Overtaking an id causes your instrument to play an additional note in its loop. The instruments’ volumes are still modulated by the current number of controlled ids, but now the music reflects the history of the game as well (if you hear a bunch of really quiet guitar notes, you know that red took a lot of ids at one time, but has since lost most of them).

By customizing your adversaries’ color in single player, or playing a multiplayer game with like-minded folks, you can select the instruments by coordinating colors, and use Influence to make your own music. As we iterated on the music design, the music was increasingly tied to gameplay, and felt like a more organic part of the game.


Multiplayer in Influence is another example of the design fitting well with the game concept. Multiplayer was a feature we knew we wanted from the very beginning, which meant that every time we added anything to single player, we also added it to multiplayer, keeping both game types in sync. This was important because multiplayer was, for us, the most fun way to play the game, and resulted in a lot of yelling around the office during playtest sessions. It was also a boon to beta testing, as our testers played more and found more bugs because of the presence of multiplayer. It is safe to say that without multiplayer, there would be no Influence.

Id Shape

Another part of Influence’s design that evolved in an interesting way is the shape of the ids. In the beginning, they were simple arrowheads. The arrowheads showed the direction of the ids and their color, but they were all identical, and we wanted to differentiate the ids from one another. We tried to design a set of unique shapes, with each shape differentiable by silhouette, but players had to memorize which one was the fast one, which one was the agile one, and so on. The shapes gave no clue about the abilities of the ids. Also, while the unique shapes were differentiable individually, when a group clumped together, it was very difficult to determine its composition. We gave the different shapes different trails in an attempt to alleviate the clumping problem, but that just made it noisier. We finally solved the id shape problem by integrating the shape of the id with its performance in the game, so that its attributes define its shape. More agile ids have bigger, more complex cores, resistant ids have more and bigger rings around them, and faster ids have more and longer trails.


The final Influence design success that we would like to highlight is the overall aesthetic, particularly the background of the game. The flat black background we started with was dull and uninteresting, so we attempted to come up with a way to break it up.

Our first solution was to have nearly-transparent squares that expanded and rotated, creating interesting patterns when they overlapped. The squares did their job, and looked neat, but were completely detached from the rest of the design. We began to integrate the background and the game by changing the squares to circles, because we used circles elsewhere in the art, but this didn’t look as cool, and was only very marginally more related to the game.

Next, we tried coloring the background circles based on the colors of the ids in an active game. Unfortunately, the coloration was too subtle to be effective, and just made the background look muddled. It wasn’t until we had the rings follow the ids that were coloring them that the background became an integrated part of gameplay. Not only does this reflect the game (you can see an opposing flock coming because of the rings they generate), but players can affect the background, creating interesting and beautiful patterns.

What Went Wrong


In Influence, players are required to choose an allegiance in order to play the game. Your allegiance represents the cause you champion as you play the game, the reason you are vying for dominance. Your allegiance is the purpose behind your idea. Your allegiance has no gameplay effect whatsoever. It does not change the way your ids move, act, or interact. Allegiances are so separated from gameplay that they are barely even displayed (only as a small symbol on the core of the id, which can only be made out at maximum zoom). Additionally, allegiances have a lot of text associated with them, all of which is meaningless to gameplay. If we were still working on Influence, allegiances would be removed.

Global Metagame

Related to allegiances was the global metagame. The idea was that there would be a map on the Influence website, divided into territories, and each territory would be controlled by an allegiance. Then, as players competed in multiplayer games, winners would advance their allegiance’s holdings and territory on the map. The global metagame, like allegiances, had no gameplay effect. The metagame wasn’t even part of the game (we could build and play the game without ever working on it), so we continuously pushed it back in the schedule, until eventually it fell off the end, and didn’t get made. We took the fact that we could make a fun, playable game without ever touching the global metagame as a sign that the global metagame didn’t need to exist.

Single Player Campaign

Easily our biggest design error was the single player campaign. We were working with a publisher for a time, who told us that in order to be viable, Influence needed a certain number of hours of single-player content. We took those hours, divided by our approximation of five minutes per game, and came up with eighty-three single player levels that we needed to create. Naturally, we didn’t want to simply ask players to play the same game eighty-three times, so we created a bunch of extra things to add some sort of progression to these levels. We added obstacles on the play field, several alternate goals and victory conditions, even triggers that changed the game midway through. Eventually we parted ways with the publisher, and, after spending far too much time trying to integrate the single player campaign with the rest of the game, and failing, we gave up and got rid of the single player campaign altogether. The single player campaign was never able to escape the feeling of being tacked on, and never fit with the feel of the core single and multiplayer experience.

Core Vision

The final design misstep we would like to address isn’t really a game feature. The core vision for Influence, the spreading of ideas, was not something we established early on in the development process. Influence began as a prototype of a game mechanic, and didn’t define a vision until very late in the process. We didn’t even have a design document for Influence until five months into development, and when we created one, it was more a description of the prototype we had created than it was a blueprint for what we wanted to create. Our lack of focus led to several difficulties.

First, it was difficult to talk about the game to press, other developers, and even family members. All we could do was to describe the prototype, or show it, and say ‘this is our game.’

Second, there was a lack of concept art, because we had no clear direction to give to the artists. Our concept art during development consisted solely of screenshots of the prototype.

Third, our demos lacked focus. Not knowing what we wanted to showcase meant our demos were simply releases of the prototype; whatever we had completed at the moment was our demo.

We finally sat down and talked about what Influence meant to each of us. We realized we were modeling the spread of ideas, and we were finally able to pitch the game in a way that people could understand.


One design lesson has become clear over the course of developing Influence. The need for a clear core design, whether a doc, a pitch, or an idea, is paramount. Everyone on the team needs to share a clear vision of what game is being made, and have a blueprint to refer to. We now see the game design as a circle, containing all things that are the game, and nothing that is not. Once that circle is defined, the task is clear: add things to the game until the circle is full, and then remove everything that lies outside. This lesson applies to all facets of the game. Art, music, controls, and game mechanics – everything works better when it is aligned to the core design.

I realize we’ve been letting this blog go fallow, but there wasn’t a lot of new content to post. There is now!

Also, look for future posts about our experience at MineCon.
