First of all, I want to say about thing that bothers me.
The gameplay though is not bad but to make a good game out of what appears to be a clone is a bit tricky.
For now the game lacks of some unique author's gimmick. You should make something that makes game yours. Like put something that you would put in Castlevania because it lacks in Castlevania itself. Give the player a reason to prefer your game over Castlevania itself.
It could be some specific challenges, some dynamically occuring events during gameplay or something like this. Don't be afraid to experiment with the game, you can discover some game mechanics that would make a gameplay more unique and pleasant.
Anyway the game is enjoyable and main game mechanics are polished. The weapons feel just right and convenient.
Love the HUD portrait and atmosphere. Generally, visuals are not bad. (but blurry font is confusing)
Music is also good, definitely gives a gothic vibe.
