The game is looking pretty nice! There should be an indication that you can interact with the shop by pressing e in-game, I didn't know about it when I played and missed out on the whole point of the game. More variety in the enemy types would've been welcomed. Well done

I had a lot of fun! The art was good and I particularly liked the giant duck boss. The upgrade system was interesting also and I liked how it was visually shown on the player with the wisps. If you keep working on it I'd love to see more enemy variety in the smaller rooms!
