Options so far:
Damage Modifier (God Mode, One Hit Kill, Enemy Damage Multiplier, Hero Damage Multiplier, etc)

I will work on other things as I play.

EDIT 0.5: I forgot to activate Mono in the original file posted. This EDIT 0.5 should work now.

EDIT 1: I found a better spot for the Damage Modifier to be. One Hit Kill now works properly. HeroCannotDie option is added (With God Mode off and this on, you lose HP until the hit will kill you, then it negates the damage).
