Coming to Toronto between May 1st and 3rd is a competition that is far more hardcore than our own Game Making Deathmatch: it’s TOJam!
The rules: you have 3 days to make a game on the given theme. Go!

Actually, there’s more to it than that… the TOJam site is filled with all of the information that you need to know in order to compete.
