Mouse Jump is a one of a kind upward scroller which is challenging and insanely addictive at the same time. In Mouse Jump, you play a mouse on the lookout for cheese. As you collect pieces of cheese, you have to jump from one ledge to another. Your score increases by one every time you collect a piece of cheese in this endless game. If you fall off a ledge however, it is game over and you have to start all over again. The game has some unique dynamics and quick pace, and this results in many falls and this makes the game so overly challenging.

Mouse Jump has simple controls. All you actually have to do is tap to make the mouse jump, and tap twice for a double jump. The mouse moves a little in the direction you jump and adjusting to this takes a little while but once you get used to it, the game feels like more fun.
