Good game! I think it's an overall really fun experience with good combat and player movement. Pixel art was great and the levels had a good atmosphere. I knew what type of biome I was in regardless of being told. Lots of care went into all that pixel art and level layout.
The only thing I would maybe improve is having some sort of memory running in the background to know which enemies have been defeated in recently visited rooms. Sometimes I would accidentally dash or fall out of a room only to come back in a half-second later and everyone was alive again.
Beyond that, I think you did a really nice job! Congrats!
