My review:
This is a pretty good puzzle game and in a somewhat unusual move actually has a pretty interesting storyline that goes along with it. At his core it's a game where you have to sweep over every single cell on the level visiting each once. To this several elaborations are added that make it new and interesting.
The unfortunate part in my mind is about halfway through the puzzles switch from being the sort that you can puzzle out to being the sort you kind of need to brute force because too many of the interactions are hard to predict . Thus I got tired of playing it around the 2/3 point and never got to see how the story ended, although I have my theories. ?
Presentation is excellent as are the controls and quality of life. And, full touchscreen support!
