Lol I've noticed there are quite a few of us all with the same theme of being the "Boss" of the game, though we have quite different takes with yours being a reverse rogue like and mine being sorta a survivors like.
Cool game though! I really enjoyed the artwork on all the different little monster tiles. Also nice idea where the hero gets stronger after each round, but you at least get to pick the buff for the hero. Overall great implementation of the theme!
