This is very cool, I like the art, and the design is making me think just enough. I made it until I glitched through the floor outside of a boss door and had to exit and restore from a save, but the save didn't have any powerups and I couldn't backtrack to recover them.
Aw, I'm so sorry to hear that saving is not working as expected, I tested it but not thoroughly enough it seems. Glitching through the floor was unexpected as well haha, I'll try to fix both problems right after the jam ratings. The physics system is custom-made, I have a lot to improve on it.
Thank you so much for playing though!
