I don't like how when you die you restart the room with the health you had when you entered, you can really work yourself into a corner with that, combined with the fact that getting hit makes you lose gold, it's always better to commit suicide when you take a hit and reset the room/gold.
having more gold doesn't seem to benefit me, at least not in an obvious way. I've gotten sick of the combat and enemies so I'm gonna stop here. great graphics, great music, the combat is good for a while but not long enough
