I noticed that health and power recovery slowly then before. Is no bad or good.
But - if enemy have low health (red line), then i can't he KO. I throw very huge punches, but health don't fall less 0. Only by "low blow" or "back of the head" i KO him, no with legal punches.
Easer KO'ed enemy when he with green health (i may KO by one punch or damage him by 50-70% of health.
