Cute game and fun concept! All the art looks really nice, and I can tell a lot of care was put into it. I think the game could be more fun if there was a damage penalty, but maybe it could be more balanced to the current no-damage enemy-filled version if the player character could defend (and take no damage) as well as attack, but be vulnerable to damage while attacking. If they can't do both at the same time, the player would have to strategize and act accordingly. Also, it might be a good idea to make the collision hit-box smaller on the player character so it's easier to move through those tight gaps to the left and right of the main area.
