Let’s be honest, when I first downloaded this game I expected it to be very gimmicky or simple. As I have continued to play it, I am increasingly surprised at the complexity of the puzzles, but have been relieved the puzzles are not the ridiculously hard kind that sometimes accompany games like this. The puzzles are challenging, yet after a few tries and you can normally figure out how to make it work. Nonetheless, new elements are added as you progress which make the puzzles interesting and challenging without being overly frustrating or tedious.

I’ve only played about a dozen levels, but am enjoying this game. I feel like a digital rat in a maze in a way, maneuvering my way through a gravitationally fueled puzzle. You don’t need to be able to read or hear, but you do need a basic understanding of gravity. An intelligent game with a clean, elegant design.

I downloaded this game a few days ago before it was free and thoroughly enjoyed it. With the v1.4 version, they have made it free and added ads at the bottom of the screen, which is very distracting and takes away from the elegance of the interface and environment. There are also ads between levels, which also ruin the flow of the game. There does not appear to be a way to eliminate these ads and interruptions, so I will likely abandon the game and delete it. Too bad!

I would rather pay for the app than be inundated with ads. It is a good game. But now is getting deleted because of ads.I will keep an eye on this app though if the developers come to their senses and realize a large portion of us just want to play, not wait to cancel ad, and then the extra steps to get back to the game if you accidentally hit the screen and get taken to the download page.
