Very cool concept for a game, simple and attractive. I liked the little puzzles as it aims to a much wider audience. I like the grid idea and the flipping of the screen it makes it like a solo coop adventure. The only thing I would say is that several times it said I would move 4 squares but I only moved 3. But that's a minor bug that I worked around. Great game though. Would definitely be cool to go on google play as you suggested!
