So I've seen a couple of these tehtered games in this jam so far - but this is the first 3D one I've seen. I'm going to give you the same feedback I've left on the other ones - I think it would be a lot easier if the controls were screen relative instead of character relative. It seems to me that having WASD control whichever character is on the left and arrows do the right character would work out better. I could be wrong, but 2d or 3d it's hard to keep track of which character is controlled by which side.
You at least do have the UI that shows up above their heads but you start to tune out stuff like that and then have to keep referring back to it when you go to move someone.
Nice art work by the way.
