Cool game.
There are four characters which each of them have their own personality and funny dialogue. The game is up to four players. I use to play with my brother and friend on this game. So my advice is go out and buy this game but the bad thing is the game is getting old. Still the game is fun.
There's a level editor with the game. In my opinion I found the level editor quite complicated but can be good once you get to grips with it.
There's 3 difficulties Easy, Medium and Hard. I completed this game on hard mode. Also there is another mode called torture chamber which seems impossible.
