What can I say, except wow. This was excellently done. It's simple, with a great interface, plays well, with a unique look that's easy on the eyes. There's a lot of challenge in the game-play that adds to replay value. The shortness of the game makes it fun to challenge friends or yourself. The puzzles require a lot of thinking and engagement. Mute options make this great for playing without disrupting others or getting distracted, I always love that.
I don't hand out the full five stars very often, but you earned it with this one. It's a good, clean, simple game that looks good and has room for more variations. It reminds me a lot of the Shift series. Great job!
