Crates is a three dimensional puzzle game. It consists of missions that consist of levels. To pass a level, you must move player to the exit by interacting with the different kinds of crates in the level. Before that you must also collect all the keys and toggle all the toggles that the level might contain. Every level has a password that makes it possible to continue playing from that level whenever you want, but if you want to get your name in the hall of fame, you must play the whole mission at one go. On that case, the faster you are, the better is your position in the hall of fame.
