1. It's not very clear that all enemies can hurt you but you can only hurt enemies of the opposite color.
2. Controls in this form is a bad idea. It's nearly unplayable on my laptop because I can't use mouse functions and the keyboard at the same time. Also, there's no purpose to moving the mouse, so why is the attack bound to left click?
3. I thought it would be interesting, trying to mediate a conflict between two warring factions, but instead it's a typical survival game where you fight as long as possible.
All in all it's a game that I was heavily disappointed by, for the above reasons.
