Really cool idea with a lot of potential! :)
I really liked the pixel art and the attack and damage animations. The character movement feels a bit too fast to precisely control at times. I think I only reached room 3.
Maybe you could showcase your animations with some GIFs or screenshots on the game page to show them off! Also, the control instructions are a bit hard to read due to the low contrast. Adding the explanation to the game page as well could make it easier to find.
If there are any more enemies I missed besides these two, let me know. I’d be happy to see more of it! :D
