I liked the game A Difficult Game About Climbing. This was an attempt to imitate it.
The hands do not copy the movement of the mouse, the mouse only gives the hands an impulse to go in a given direction. As soon as the mouse stops, gravity pulls the hand down. That's why I put Ragdoll in the name. We don't control the puppet. We just push its hands :) I thought this concept was fun, but the controls suffer from it. I'll probably redo the whole thing.
