Due to the weird screen size and my inability to quickly find a tool (preferably open-source) to crop the video, I don't have YouTube video(s) yet, but here are some screenshots from our game, Horizon:
(not actual size, I don't have the original on this computer)
We used the Ouroboros theme as thinly connected to Quetzacoatl, and more heavily connected to the link between player 1 eating stars and player 2 making buildings...and if they fail to get enough sacrifices, not enough stars will be respawned, and Quetzacoatl will fall out of the sky.
We had a programmer (me), and artist, and a guy who ended up doing mostly sound. We prototyped a different game on Friday evening, threw out everything Friday night, and I believe almost everything besides some Game Maker scraps and a little code is from Saturday morning onwards. We also tried to get 5-6 hours of sleep each night in a nearby hotel, and even had time to go out for food.
The music isn't super fancy, but I think it's neat since it was the guy's first experience with Garage Band as far as I'm aware. He made it using the iPad version, recorded the (hilarious) vocal sound effects on the iPad, and I used bfxr.net to generate the other sound effects.
It's about a 10MB download for the .exe. It's probably best with two players, and you definitely want audio to hear the sound effects. However, if you're really coordinated with both hands, you could play it singleplayer.
If anyone tries it, let me know what you think! Altogether it was a fun experience, I finally got to meet these two particular internet friends (my teammates), and everything meshed together quite well even though we basically started over on Saturday. The best compliments we got from other people were from two playtesters, who sat down and then played it like 10 times over (while we still had submission stuff to finalize), and from the audience when we gave the presentation, who were laughing at the sound effects. =)
It's late so that's all for now. Another day I should try to post some more thoughts on the event, things we did, things I may have learned, etc.
*edit* We also had these two diversifiers:
Asymmetry: (Every player is different) The game requires more than one player, but each player has entirely different goals and rules.
Collaborative Casual/Hardcore: (Two players: one casual, one hardcore) Collaborative play for two, but one player has more to do than the other (or the difficulty level is different between them).
*edit again* Here's the download link:
