Going to do the compo this time round.
Will likely be in Unity, and depending on the game, I *might* possibly use Twine and the Twine/Unity parser thingy I made for http://makerseden.screwylightbulb.com/ – it’s nothing too fancy, but we do plan to release a starter project for people who want to make similar games. Graphics will be GIMP/Blender.
No idea about sound… might just record some armpit farts and call it good.
See you around this weekend – have fun.
