When you play a puzzle game you expect an actual puzzle, not one where it basically has a very short, simple, liner path that leads you to the end with three "feel good" gold stars. I'm not trying to knock your work but the major problem which really killed this for me was the lack of a challenge. It had almost no challenge. I went up to level seven and I just couldn't stand any more gold stars spoon fed to me. Anyway let me list the good and bad.
+ Cute Visuals
+ Decent SFX / Music
- Way too easy
- No real "puzzle" here
- Lacks evolutionary desire (meaning it doesn't give you a reason to want to continue)
Remember - when people play a puzzle game its so they can get a slight brain work out while having fun solving a puzzle. Maybe the age-range for this game is two to four but honestly it wasn't fun nor rewarding. I felt bad accepting three stars for everything...
For future work I suggest making your game a lot more challenging and "puzzle worthy".
