In 2008 I was searching for physic/rag-doll game's because I was bored and wanted to play something bloody/violent to take stress out on (instead of punching someone who was making me map at the time), and ended up finding this.
Seihareach: Linerider is a game where you draw a line and have a rag-doll type person ride a sled on the line, there are other version's I'm just naming the sledding one.
