I love the narrative progression of the witch getting more aggressive as she takes more damage pretty clever use of game play. I think the player movement was to restrictive with low move speed and very low jump height.
Though if that was on purpose for the sake of the game's narrative of her getting more angry and serious I think her move speed, jump height, and magic ability could be improved as she gets angrier to vary the gameplay and add more excitement to the game.
I found the game peaked my interest as the witch's demeanor changed as she took damage. I think there's good story material here to expand upon.
