Alternative ways of control
I'd like to see another way to control joints, not because it'd be more comfortable to play with, but because it can often be a nightmare to click some of them. When the two players grab each other is not the worst, however. The worst is that the game doesn't seem to register collisions between different parts of our own body very well, and they overlap each other.
This is a nice example:
Err... don't even ask how that happened.
Another problem is that controlling the camera vertically could be easier. The only way to change the vertical angle as far as I know is to hold shift and use the arrows keys. It would be way nicer to control such angle by pressing the mouse wheel.
Anyways, the thing is that we need either to improve both collision and camera control, or give an alternate way to control the character. A small lateral representation of the character in a normal position that you can click would be a good option, for example. But please give us a way to control our characters efficiently.
