Candy Smasher iOS Game

Helloooo !
I had the opportunity recently to work with a developer, Pradeep Rana, that wanted to create a game called Candy Smasher. This is my first time designing a real game! So I'd love to get some feedback on what I can improve, for next time :D

Feel free to download the game at:
