Puzzle mode is really challenging, yet fun.

I hit a wall at level 15 in puzzle mode. Finally, after too many attempts, finally solved it in 6 taps. Now, Im at level 25, and its been challenging all the way. Arcade mode is a blast as well. Music is repetitive, but thankfully you can lower the volume to your taste. Very colorful graphics, smooth responsive controls. Best of all, theres a lite version to try first.
