Great demo! Wonderful art and music! The atmosphere is spot on, I love the tree library theme. Each power-up being a well know story book is pretty neat. The jumping feels a bit odd, it feels as if gravity is super heavy as letting go of jump makes you plummet to the ground. Combat is a bit lacking, It would be nice to have a satisfying sound effect and maybe a bit of recoil. Also The boss fight was elementary easy. I really like it so far, it's got a lot of potential!
