Gameplay
Gameplay
The player controls a cat who must rescue their love interest from mice. The cat must navigate a series of single-screen platform levels through ladders in a manner similar to Donkey Kong (1981). The cat can capture blue mice by touching them, but pink mice defeats the cat on contact. Pink mice throw a plethora of objects such as cheese, bouncy balls and bombs which kill the cat on contact, but can grant points if jumped over. Catching enough blue mice will spawn a ladder that allows access to the top of the level in order to complete it. Fish appear throughout the level and grant bonus points depending on their color.
