I like the idea and the graphics present your theme very well. I don't know if it was part of the game because some things not working right is  supposed to be that way but striking doesn't work sometimes

I loved the glitchy effects on this one, at least if a bug happens you can say it's a feature!! Also pretty neat that you made the parallax effect on the background but inverted(???) idk if it was intentional but it fits with the theme of the game too

I'm pretty sure I've seen the main character sprite from a tutorial somewhere. It's pretty easy to cheese the attack cooldown by waiting a moment between swings, unless that was intentional, but it wasn't very clear.  Also PLEASE speed up the dialogue boxes! Or let the player speed them up by pressing a button. The only thing stopping me from beating the boss was the tedium of having to wait through the dialogue every time.
