You wander the floors of an office building, clearing furniture and hunting for usable items. It's tricky, as there are lasers, electrified walls, and mobile sentries to avoid. There is a story, told in voice messages you find occasionally.
I found the game to be great in small doses. There is no option to save, and there were a few times that I quit rather than finish my game.
Playing with a small kid is a bonus, as they'll excitedly alert you to dangers and make desperate suggestions.
I'd pay a dollar for it easily.
