A very good game, the AI of the enemies is very well done, the design of the game (and the UI) is very cool, however, I noticed some optional aspects that the game could add:
1) A tutorial to tell you the controls (they were intuitive, but maybe for example I had the possibility to change the weapon between snowballs and lollipop (to save the snowballs for later) and I didn't know if I could do that.
2) The lollipop attack is good, but it's a bit strange that you have to stick to the enemy for it to take damage.
