This is an AMAZING auto battler! Why haven't I seen this before? There's a lot to unpack here, the different characters, the halloween theme, the way you can customize your own mask adding different powerups by just sticking them to the face, the art style, the stats, the boosts, the tech tree... that was A LOT for a game jam game, good job!
I'd polish the UI a bit and make it a full released game. Keep in mind you can enlist your game for the halloween sale! This is a cool halloween game to get for a few bucks. I'd give it a try if I were you. Good luck!
