I'd rate this game a 2.5/5 overall. I appreciate the effort of this not being a clone puzzle game. The game features 3 sets of puzzles minimal,challenge, and timed. I found the timed ones to be very annoying after the first few. The other two modes were decent, but what we have is another game with easy GS that you will soon forget about. The puzzles over all are ok but far from addicting. I'd recommend buy on sale if you are a fan of the puzzle genre, or easy GS.
