In this novel puzzle game, you must maneuver MSB, a maintenance droid, around the damaged ship Rasterscan to avert the impending crash with a nearby star. MSB must solve numerous logic puzzles to gain access to other areas of the ship. Most logic puzzles involve eight blocks arranged in an octagon, in which you have to swap the colours about until all of them are yellow. It’s nowhere near as easy as it sounds, and once you’ve started the puzzle, you can’t exit from it until you’ve finished.
