Here's my game for the jam: The Necrommando!
It's a light-gun style shooter with roguelike elements. This was my first attempt at procedural generation in a game and I'm pretty pleased with how it turned out.
EDIT: Nevermind. I pulled the game. Some features weren't done in time for the jam deadline and I didn't win anyways, so fuck it. I guess next time if I want to win I've got to make something original like a pixel-art platformer.
