Wow! Absolutely amazing atmosphere in this game, incredible! It's so magical and atmospheric with the particle and sound effects all tangled together, it really does work amazingly! The graphics in this game are phenomenal and just create a really cool vibe for the game. Something a bit jarring was the player glitching a bit into the wall. I'm not sure if this would help, but maybe a 2D Circle Collider on the character could help fix it if you haven't already? Not entirely sure, but might be worth a shot.
Overall, amazing entry! I really enjoyed this one!
