It took me about a minute or so to figure out what was going on with the electrons and to swap polarity for attacks. I couldn't figure out what the anvil with hammer in the middle was actually doing or for, as the bar never seems to fill up? I'm also curious, from the win screen, what was expanded for this jam specifically, since it was built for Ludum Dare 55? The crystals were also a nice touch to help clear.
With that said, the feeling of the game is great. The art is stellar, and I would love to know how you accomplished this sort of lighting. The audio was on point and very good. Great entry.
