The game is well-designed from the very first level. The interaction between the magic spell and the layout is attractive and fascinating. The citation of free sound is also worth mentioning. Besides, the dying effect that the witch gets erased from the scene is a cool concept. However, the game could be improved in certain aspects. First of all, the scene could be decorated by using sprites instead of solid color blocks. What's more, hint on the effects of spells should be given that people who didn't see the game trial might be stuck in the first level wondering how to use the spell. What's more, the interaction between the witch and the platform could be elaborated further that the witch is always stuck at the side of the platform. In addition, the UI might need further polishing including the potion and health bar. There is a little problem that after losing all the health, the witch can still jump which can be fixed easily.
