Nice! The game is getting more and more entertaining with each update.
One suggestion, I think it would be nice to have a way to restore your health over time. Not too much, just enough to keep you playing. For example, you could heal the player by 5 points on start of each level.
It’s rewarding when you get to 1% of health in a fight, but you don’t give up, because you know that there’s still a chance for survival if you stay alive for long enough.
