The game as it self and the levels are quite amusing.
Although, one need to watch endless ads if one wants to play more levels than the first 9, unless you dont buy these free. Thats extremely annoying, as, additionally, you can just watch two ads a day, so play only two levels every 24 hours.
Also, the game is not what one could call bug-free.
