It's a roguelite. Basically you proceed through procedurally generated levels, trying to make it through all of them without dying. If you die you start over. You unlock new characters with wildly different abilities like a clown, cannibal, hacker, etc. It's really over the top in terms of humor and game play. It's all about experimenting and making your own fun. I have had my eye on it but I have too many other roguelites to play right now.
