Game with clear inspirations in Castlevania, aesthetically the game looks quite pleasant with what is a Dracula castle theme, only with shadow demons instead of more classic monsters.
Mechanically the game feels a bit heavy and not very responsive, perhaps it was the lack of range and that everything took multiple hits to fall unlike titles like traditional Castlevania where only a few well-delivered hits were enough even if they completely stopped you from attacking and had a delay between starting the attack and carrying it out. Another option might have been to stop enemies a little with an impact, but overall I didn't get used to the movement.
For a jam game it's pretty good, it could be polished a little, certainly a good project done in a short time, although to be done in a vampire-themed jam, the game lacked more vampire themes.
