Most annoying glitch - shouldn't pressing R restart the fight you're in, eg if you're starting with a boss, rather than restart the whole game?!
Smooth controls, good music, good balance of difficulty on the "hard" version, which is nice! The betting feels a bit low-stakes - when you wager and lose, actually don't lose anything except the time you took on the level, so there's no sense of jeopardy. Not sure what you can do about that unless you suffer a temporary loss that you then need to go and whack some monsters to recharge - which just brings back the "farming" you didn't want.
I know it's a LD but could have done with a more satisfying ending than that :p
