It's a really good looking entry, with very nice pixel art (especially the parallax background at the start!) and animations. Kudos on that! Strong Blasphemous vibes too!
Sadly I didn't get very far into the castle because the controls really weren't working for me and it didn't seem like I could change them. I expected to be able to move with the arrow keys, but couldn't. I had to switch my keyboard layout to QWERTY to be able to move correctly with WASD and using the other side of the keyboard to attack was not natural to me at all.
This means I really struggled to fight enemies. I started to explore the castle but did not find any checkpoint. I died after fighting a few enemies (all different and cool-looking!) and was sent back to the title screen, so I gave up.
Gamepad support would go a long way in making this entry more approachable. As it is, it looks really good and is quite intriguing. With more input mapping choices and some player onboarding (tutorials and such) it would surely make for a nice little game! Keep at it ;)
