Thank you! Hm... I guess I could have made it easier in that way too, its been really hard to balance the game :P
Oswald had 3 bars of health, like the other civilians, while enemies had 4 bars of health. I guess I wanted to make it such that while you get an upgrade, it is easier to kill enemies but also harder to protect Oswald or something.
Anyways, thanks for the feedback, I really appreciate it!
