Billy has been kidnapped by aliens, so your task is to help him escape their prison and spaceship, without taking too much damage so that the aliens catch up to him and grab him back.

As you proceed to the end of each level, give it your best to collect as much cheese as possible, so that you amount to a really big score, and solve all the puzzles you encounter in order to advance, since the path is not that clear. Billy's face is magnetized, so he will be able to collect cheese easier.
