I think the art style of this game is really polished and I really like the light effects of this game. Everything fits pretty well together. Details like the death animation, background movements, glowing effects around the candy clearly suggest a high completion of the game.
There are some minor bugs: I died when hitting a normal tile with an enemy on it; the pumpkin didn't disappear after death. The level selection menu and the pause menu can be improved by making more sprites and using the same fonts. More bgm can be added in different scenarios. But overall the gameplay is pretty satisfying and enjoyable.
