the art and animation is seriously impressive! It reminds me of Blasphemous. But your game is seriously lacking in the other departments. I think you misplaced your priorities this jam. this level of attention to detail should really be something you do when you have infinite time post jam. focus on your mechanics!
the gameplay was pretty unimpactful and one-note, the movement looked jittery(not sure what's going on there exactly), and the boss was way too easy to cheese. this could be really great if you add some more depth to the combat. try dodging through enemies, grabs, blocking, maybe a kick that doesn't do much damage but pushes the enemy back, there's lot of stuff to try in a melee combat game like this and it would look great in your art style.
keep it up, but work on improving your process.
