All things considered, I'd say it's coming along pretty well. For controlling the characters, all forces are applied to the torso which has given pretty smooth movement. Any attacks though, those apply their force directly to whatever limb they touch, so that's how you get the limbs swinging around when punched and what not.
Thanks for the interest!
How's this game coming along? It's looking cool, are you just applying forces to joints to make the characters move around? I like how their legs break when they land sometimes.
