First of all, I love the art style and the music, great job on it ! Also, that shadow idea is really unique !
However, the platforming feels horrible imo (Too much time to accelerate/decelerate, I think; I personally prefer snappier movement).
The controls are also not the best, I think that assigning the jump to the Space Bar and the attack to the Left Mouse Button might be better.
Pair the two points mentioned above with the fact that you can literally fall to the beginning (Talking about that chain section + the wooden area after it), and you've essentially got yourself a rage game.
After getting 3 of the ingredients and 10+ attempts at that chain area + the wooden area, I just gave up, and I apologize for not finishing the game.
Of course, this is all my personal opinion and, to be honest, I'm not the best at platforming but I can definitely see this being a great game for someone better at platforming, so, great job !
(Also, those bats are really annoying)
