This was a fun playthrough. Nice sprite work and animations. The running and jumping felt pretty good. Combat was okay but could use some tweaking. I ran into issues others described. Also, a small amount of knockback would be welcome. I feel a little bad killing some dude just trying to play piano though :P Anyway, good entry and good start to a cool game!

The Player run animation and game mechanics was good,
Player attack hit box was not at the right spot sometime I just happen to miss the attack

Anyways, good work!

It's nice to see the castlevania side of the genre being represented. The game looks good, and even more so it looks cohesive. none of the assets felt out of place. 
I had some trouble with the combat, I got stunlocked by some bats a couple times and after wasting some fireballs I couldn't figure out how to refill them, but that could also just be me, lol.

It is very easy to get stunlocked to death without being able to move

I do like the character sprite
