Stair Dismount

From Wikipedia:
Stair Dismount (also known as Porrasturvat) is a computer game originally made by Jetro Lauha of tAAt. It is a puzzle game where the goal is maximising the 'damage' done to a 3D stickman figure; the player causes damage by applying a force to the figure to make it fall down a staircase.

The stick figure's falls are accompanied by various sound effects (cracks, wails and groans) as it makes its way to the bottom. Stair Dismount uses ragdoll physics, so the figure is very floppy as it falls, like a ragdoll.

The game was first published in Assembly 2002, where it won the first prize in the game development competition.
