Want to start by saying the art is amazing, I can clearly see the vision you're going for, a little feedback would be to increase the attack range by a little (when attacking from the right) or make enemies get knock backed away from the player when hit, this is especially noticeable when enemies are coming from above as they can collide with the player before being hit themselves. I did get the feel for kiting the enemies, but it can be a bit frustrating for more casual players. The attack animation when attacking from the left side bugged out for me therefore I tried to position myself so they either come from right or below me. Also I was a bit unsure what exactly made me progress to the next level, by killing enough enemies or by surviving for a period of time, I would've liked a visual representation of that on the UI.
Either way very awesome job on the visuals, the game does have an artistic hook and the setting for the story is also there, would really enjoy to just play more of this game as it was fairly short :p
