Good game!
Liked the visuals and the concept.
The fighting mechanic feels kinda bad though tbh, weapons feel slow and unresponsive, and enemies feel unbalanced like why a rat doesn't die from one hit of a sword?? I don't know if this is the intent but unless you hit and run (which isn't fun) you will always lose health even against one rat.
IMO , it would be better if you made the player stronger to the point where he can kill small enemies with one hit, you could also add a block/defence ability.
