Very good art and animations! It's also very impressive that you managed to get cutscenes and dialogue working in the short timeframe. Metroidvanias are some of the most difficult games to make in a short game jam, and you managed to do it!
The gameplay could definitely use some polishing: the basic attack could use some more reach, as I kept getting hit by contact damage while trying to attack enemies, and the jump could be less floaty; it was difficult to land on platforms consistently (but I did notice you added coyote time which helped a lot with the platforming!). I'm not sure if being unable to turn around mid-air was a design choice or accidental, but I think that triggering an attack or dash at least should turn you around.
All in all though, a very good metroidvania, especially considering it was made in only 9 days!
