Not really a game I know but I saw other people submit drawing tuts, be them a bit less crude.
Just how to draw a one point perspective view from above objects. Simple I know, I spent all morning on it though. I'm not a very good artist, but I remember being taught this in school, thought some people might not know.
Either way it's a good time killer if you're bored in school or something, and if you have patience it doesn't take skill since you can use a ruler or line tool. It's really only as complex/difficult as you want to make it/can like most things.
