The most honest five stars I have ever given.

This game is so long for what it costs! Not only that, the graphics are amazing and there is even a “level skip” system that is so good for players like me, who can grasp the basic concepts, but not all of the more complex and nuanced actions, who can just skip the levels with complex solutions that we don’t entirely grasp. The App Store needs more games like this. Great work to the developers who were able to package this amazing piece of eye candy and a weeks worth of brain teasers in such a small package (that is, my overcrowded and old phone) 👍👍👍

Challenging and Engaging

A real challenge, but once you get the hang of it, it is immense fun. I have beaten the game (it took a while, as it has many very different levels) and I continue to replay because it's so enjoyable. It racks your brain in a good way. Very unique--unlike any other iPhone game I've played. I super recommend.

Sheer brilliance

I have been an avid iOS gamer for several years. This is by far my favorite puzzle game that I have encountered on the platform. There is something incredibly satisfying about mastering its various mechanics (which are rolled out brilliantly) and putting them to use. Please support Kenny and family.
