Very nice! Great animations, good music, and an intriguing mechanic that feels quite fresh and original. I really like how you retain a little bit of control even while the character is breaking down; it allows for some interesting risk/reward behavior. I think your range is even greater with the helmet than with the guy if I'm not mistaken and sometimes I ended up using that advantage to hit enemies through walls. Not totally sure if that's intentional or not, but I definitely think you should take that idea and develop it even further. I'd love to see where else you go with this concept. Great work!
