Thank you for the feedback. A friend of mine that playtested pointed exactly the same things about the money, and sent me a screenshot of little shards out of bounds with the caption "You are evil." He also asked for a "increase pick-up magnetism" upgrade, saying his "little monkey brain" would appreciate the dopamine.
I've decided to take notes on all the feedback from this jam to work on a non-jam version of the game. I pretend to include bosses between levels, more enemy types, 2 new movesets and light orb variants, rework the upgrades and shops, make new art to make each area unique and add all the standard accessibility features that are missing (like controller suport and key rebinding)
