This is really cool!
Really liked the overall idea behind the game! I enjoy a good wave/base defense style game, and this was hitting just the spot! Only real critique I would have is that it felt like I had to get real close for the "Give Candy" pop up to show up on the enemies for me to damage them, and that usually resulted in me having to hurt myself too. Luckily there was plenty of health pick ups around, but it did feel a little off. But I may have just been missing a key mechanic as well.
Overall though, incredible job! I hope you're proud of what you made!
