Nice puzzle game with a nice rendition of PSB's "Surburbia" on the title screen. It reminds me of the Future Composer tune by Beat Machine, featured in Cruel Crunch V2.0 by Beastie Boys.
The game itself is addictive. There are some minor bugs in the production related to the in game sound options in the settings menu. I tried to play music but it was all silence. Still don't let this put you off. You have developed a nice game, and it is pretty addictive. :)
