Geroneko

Geroneko is a nonsensical Japanese 2D action game. In "the month of 2X157", Earth is destroyed in an explosion, launching all of its animals into space. One such animal is the titular Geroneko, the "ultimate companion animal", who flies through space aboard his tuna-powered Mug-Rocket. In order to create a new planet to replace Earth, Geroneko must shave all of the floating animals he comes across so that he can construct the new planet with their fur. To complete each level, Geroneko must shave every animal (by colliding with them) before they can be sucked into the black hole in the middle of the screen. Geroneko's Mug-Rocket has limited fuel, but can be refuelled by collecting cans of tuna. If Geroneko allows any unshaven animal to fall into the black hole, if he falls into the black hole himself, or if he collides with one of the dumbbells floating around, it's Game Over.
