Hello, welcome to Totally Mad Game Jam. Your task is to create a game under 48 hours. Try to make the most crazy game. The topic will be chosen at this and you have enough time to think about it. So, good luck (if you don't win, break your neck).  And above all create something playable in the browser, and not to start lagging the whole PC!!! And please, don't use WebGL.
