Mountain Maniac

This is seruously one of the funniest flashgames I've ever played.
You're the "Mountain Maniac" and you're really pissed. So you decide to throw rocks down at the town below you. The graphics are REALLY simple but does the trick extremely well! The music and sound effects are also great.

This game was made by PixelJam who have made a lot of great games.
