Thanks for playing and the excellent feedback and suggestions.
The camera shouldn't rotate unless you use the arrow keys? I'll check.
The punching is more of a last resort. You get few points and little damage. It's just there as a backup plan currently. Needs to be balanced. One way it works well is to be aggressive and go after the enemy. They will be more defensive and try and evade instead of countering.
Yeah, the physics needs tweaking because it is all purpose code right now, meant to work for 2d/3d or even third person / FPS.
Jumping felt weird, yes. I tweaked the jumping. Little better
