Incredible! I get a huge amount of hollow knight vibes from this and I absolutely love hollow knight so this was a joy to play! Some small things to consider: Some more visual feedback when you attack enemies would be nice (maybe a small black particle effect). I feel like my attacks don't "feel" as strong without them. A jump SFX would be nice as well. Also some hitbox bugs that you mentioned in other comments. Otherwise, the game looks really good, the music is great, the amount of enemies you implemented is amazing, and was a really fun experience. Great job and good luck with the jam!
Edit: I don't wanna be that guy but do you think you could check out my game as well? I really looking for some more feedback for my game but I've only gotten a few comments of actual feedback haha. It'd mean a lot if someone of your caliber could give me some more bits of feedback!
