Try to touch the yellow cheese. You will gain Bites of Cheese. Try to get a high score of more Bites of Cheese, and avoid the moldy cheese. You are the Mouse, and the Mouse will follow your mouse-pointer. When you are on the GAME OVER page, to start a new game, press the space bar. You start in game over, press space to start.
I created this myself, and I got the inspiration from another game I created, called Dragon Tag.
