Wow, I have basically only glowing compliments to give here! Your map is so well made for showing points of interest and backtracking as you gain new abilities. Your animations are great, and the environment and psychedelic living background are such a vibe. My only note visually is that sometimes the player character's body, because it is black, disappears against background stuff. I also noticed this issue a couple of times with the dark blue flying enemies; sometimes I didn't even see them until they were lunging at me. So lightening those and the player's body up a bit for better contrast would probably help a lot.
One gameplay thing I encountered was the pink shards sometimes could fall and clip through the ground collider, so they ended up out of reach. This was pretty rare, though, so I didn't feel too ripped off and the bulk of them were fine. Everything else gameplay wise felt great and fair. I haven't quite finished the game yet, and finding a new area and realizing how much more there was to explore made me really impressed with how much you accomplished for this jam. Awesome work, definitely one of the most enjoyable games I've played in this jam!
