Great game. Simple concept and good looking.
The only thing that made me give this a 3.5 out of 5 stars is the upgrade mechanics. You grab many big candy packs and only see candies inside them. When you have thousands of candies and one pack with perks finally appears, you have the option to choose between 2 lame ones. Then you reach first boss with 2 lame perks and 1 that's is actually significant to my playing style. If perks were even more rare, but the player could choose ONE perk from ALL perks, this would be more of a strategy game, rather than a luck game. Some people enjoy the luck game style, though. Some people like replaying the same levels until they are ready for the next challenge. That's not me, "lucky" and "replay massively" factors are really bad for me.
That's it. Cheers! :)
