This is an invincible version. Cat Mario is a very difficult Super Mario Bros like game. You are a white cat and you try to go as far as you can but there are enemies lurking at every corner. Platforms fall at random and when you think you are about to get a power-up, it turns out to me an enemy. Your only defense is to jump. This is a super-difficult spin on the SMB games that we are accustom to play. Don Play
