great job on this! really loved all of the enemy behaviors and the boss i got to. the upgrade rooms were handled well with them requiring you to use the new item to get out. on the art side, i feel like the music got pretty grating in the first area not long into it. the enemy attack particles are incredibly hard to see both due to their size but also their contrast with the environment. the contrast was low in general but not so much so that i couldn't see what was going on outside of the enemy attacks. the character controlled well and i never really felt like the computer had slipped up or anything. there's also just a lot of content in general, lots of rooms and enemies and upgrades for a jam game. enjoyed it overall!
