Nice job! Mechanics are on point, very very nice music. I liked the art and the vibes, and the storyline twist.
Is there a way to upgrade the sword at the shop? The magic upgrades are so OP haha.
Only potential improvement I can offer is that the screen felt just a bit claustrophobic. The player and enemies were maybe a bit large and moved too fast, so it was harder to see what was coming and I didn't get as much of a feeling of cleaving through giant armies of enemies as what could have been.
Still a 5 stars from me for an interesting concept and fun gameplay!
