I'm sure you guys suffer from the same interests as me, and as a result, i'm sure you enjoy flash games. On said flash games, its simple, its fun, and you can play them at work.
Well, have you tried Everybody Edits?
The game is just as the title implies. Its a platformer anyone can make and anyone can love, whether a player or a creator its all good fun.
Give it a try, suggest a level or two.
