Here's a trailer for Not the Robots, a stealth game where you control a robot who must eat the furniture in a procedurally generated office building. The furniture you're compelled to eat also serves as the environmental cover needed to sneak through. Clever stuff.
The game is planned to release on PC, Mac and Linux (through Steam) sometime in mid-December and I hope it's as much fun as it appears. Developed as part of the HouseOGames incubator program, designers Eli Pililonen and David Carney have a history of making fun Flash titles (I love Viricide) and this marks their first commercial release. Looks like it's coming together pretty well for them.
