Nice entry. The aesthetics were amazing. The game make for a good start for a Castlevania like.
But I have some remarks: The platforming wasn't good (The player feels non responsive). The Boss feels boring, it's just a hard version of the skeleton that have a long health bar. A bit of transfromation when he lost some health would be good.
Overall the game seems good, I hope you continue developing it.
Congrads for the submission.
