Rats are flung across the screen, and they must be sliced apart to earn points. Slicing multiple rats in one motion results in a combo, causing more points to be gained. Grenades also fly across the screen and must be avoided.
Spring Razors can be used to kill every rat on the screen.
Additional content such as different blades, backgrounds, music, and other items to slice, like hagfish, can be unlocked by progressing in the game.
