This game is really good. I played through a few times but the wizard always got me in the end. My favourite build was a quick long range jab on the right hand and a massive slow powerful hook on the left.
The way you can choose which hand gets which powerups makes the game surprisingly complex and it could get even crazier with a few more powerup types. Its great how they all work together, reminds me a lot of the Binding of Isaac (just a lot less gross). One idea I had while playing is that maybe an upgrade could reduce the damage of the punch but makes it apply a debuff to the enemy to incentivise giving them the ol' one-two.
The theming is great as well. Making the link between the classic rectangular dungeon and turning it into a boxing ring is brilliant.
