The Cat Machine

The Cat Machine is a game of logic, and cats riding trains. The premise: Earth's stable orbit around the sun is maintained by an enormous secret underground machine where cats of various colors ride trains. Without this mechanism, the planet would fold in on itself with a satisfying pop and cease to exist. You are in charge of designing that contraption.

The puzzle rules: cats can only travel on tracks the same color as themselves (of course), the cat at the front of a train decides where the whole train goes, and once a cat has traveled along a colored track it flies away (as cats are well known to do). The goal for every train is to make all cats, including the white one at the end, fly into the ether.

Over fifty levels stretch the logic, and the game uses high-fidelity 60fps Advanced Cat/Train Simulation Technology for maximum cuteness. Rock Paper Shotgun called it 'fun, fast, colourful' with humor in spades. Supports Windows, Mac, and Linux. Beautiful music throughout.
