Unless you're one of those idiots who call games like 'Candy Crush' a "PUZZLE" game, you'll get the hang of this game in a jiffy.
It'd not too difficult, but is still challenging enough to stop you from getting bored.
Only complaint is the huge cool down on locked levels, and the fact that the IAP is too much for 32 levels. I'd be more inclined to buy it if I was assured it was going to give me access to future levels, and not just the 32.
