Naughty bear: the day bears go ape shit on each other

[GrooveMan.exe]

Actually, the game doesn't encourage you to outright kill these bears. To get the most points, you'd have to drive them to suicide. At least that's what an early interview stated.

So it's Mad World... but in Reverse?

That actually sounds like considerably less fun. If I wanted an emotional torture simulator I'd play The Sims. Or Rollercoaster Tycoon.
