The animation for the player is really cute, although it looks like the health bar is attached to the same gamobject as the player sprite so when the player turns around the health bar does as well. I kind of wish the player moved a bit faster but that may just be personal preference. It took me a while to figure out that the final boss was a tooth with a tooth brush but its really well done. It would be nice if you had some mechanics for the final boss, like you have to make the boss hit some large pieces of candy so it gets a cavity and dies/can take damage from kicking.
