The game casts you in the role of Jerry Mouse, trying to navigate your way through a multi-platform maze on each level to grab pieces of cheese and then make your way to the exit. The arrow keys let you move around and jump, but your job is complicated by obstacles such as spikes, walls, and of course Tom, who will cost you one of your life hearts if he touches you. Lose all your hearts, and you’ll have to start the level over.
