Fun puzzle game, simple mechanic, but good puzzles, sometimes, sometimes hard levels are followed with trivial levels, but all difficulty levels are present.

There are 80 Levels for 2 Players and 40 for 4 Players (Or 2 Players, which control 2 Charachters each)

The Achievements for finding secrets have been broken since an update and never got fixed, so thats pretty sad. You can downpatch, but its just stupid you have to do that. Probably won't ever get fixed, game is abandoned.

This game is fantastic! It helps if you have a bigger keyboard so you and your friend don't fight over space if you have a small laptop. Other than pulling all your hair out after dying a kajillion times, it's very satisfying to complete all the levels in single player mode. You also become ambidextrous after finishing the game!
