Critter Cratez is a game that will keep you occupied for a long time

Critter Cratez is a transport puzzle game with 100 levels. The player pushes crates around, trying to get them to the target locations. The entire object of the game is to push little boxes onto little assigned marks so that every mark is no longer visible. The number of boxes you have to place increases with higher levels. The thing that makes this game challenging is that you can only push boxes and there is no pulling allowed, so if you made any wrong move you game will stuck there.
