A Fun yet Meditative Challenge I really enjoyed 3ph's second foray into android puzzle games. It has a strong concept behind it. The storyline is simple, but beautiful. As is the music. It's something that you can play either strategically or without thinking, but you'd be amazed how much work your subconscious is doing. It reminds me a lot of the games cognitive scientists use on test subjects to demonstrate how easily the brain picks out unspoken rules and patterns. Minor criticisms: I prefer playing with the sound off because the speed that I like to play makes the music sound almost cacophonous. I wish there was some special sound the game made when I win, even though I get that winning is not entirely the point. Finally, and this is a super minor nitpicky one, the edges of the squares lose some of their sharpness when in motion and the shading of the sides of the squares is sometimes uneven. But despite those tiny nitpicks, it's a good game and worth buying.
