I enjoyed your game! However, I would recommend putting more emphasis on when you take damage. I didn't know I was taking damage when I first played it. I started purposely running into enemies to see if it actually did something! (It did! Haha!) I think there might be a little thud noise or something, but it was kind of hard to hear. I think something like a slight screen shake may have helped indicate that. But overall, very nice work!
