The platforming works really well, I managed to walk around the level without missing jumps and without getting stuck anywhere which is great considering the layout is quite vertical.
Fighting seems difficult though. It's not very obvious when our character loses hp. A small animation, or camera shake, or visual effect would be helpful, as well as seeing clearly where the damage comes from. Sound effects would be great for that too!
Because the enemies seemingly attack instantly and without warning, taking damage seems to be unavoidable in order to get in range to hit them.
Wishing you the best on your gamedev journey!
