Mouse in The Labyrinth

This game is based on a simple labyrinth game. You play as a mouse, searching for his way back home. The goal is to reach the door as fast as you can before the time pass. In level 1 you got time bonus by eating cheese and picking key. While in the next one, you don't have such thing. The time got longer then the previous one, but the labyrinth got harder. Good luck with that.
