i liked it, but i have some critiques:
first and foremost, it needs sound. without sound effects it just isn't as immersive as it could be
also, the player needs a walk cycle, it looks really weird when the player is just sliding around in the idle animation
during the bossfight, the screenshake was way too much with no option to turn it down and the shockwave attack happened too often so it felt unfair
as for the itch page, the background looks weird, it lacks screenshots and most of the styling just isn't changed
