I love the art! It's one of the best pixel art I've seen this jam :D The audio sfx really ties into the retro gaming style.
I would love a tutorial page or instruction page beyond the controls! I figured out halfway that repelling/attracting the electrons damage enemies. There are a few times when I summon a mage and I forget that its not an enemy XD But I noticed you've already tried to increase the readability by using red outline on enemies (I'm just dumb).
