Download Stair Dismount
Stair Dismount is a weird but pretty awesome game that you will enjoy, especially because of the physics engine that will transform your character into a ragdoll in order to score the highest possible score. You will have to push the character down the stairs and watch him tumble down.
He is a stunt man so you will not have to worry about broken bones as he will not get any. Moreover, this game is the first one that managed to introduce the ragdoll physics engine into the gameplay in order to create one of the best freeware games that were ever launched.
