Recently I developed (along with an artist and a musician) and published on Android Market a puzzle game called Connector and would like to use this space to publish it to you and maybe get a feedback from those who enjoy games, especially those challenging (the game starts easy, but will complicate).
Your goal in the game is to connect the pieces, but without mixing the colors (yellow, blue, red and green). You can rotate, select, and swap pieces from places (those two last are only available for pieces with lighter background).
The game has many challenging levels, which guarantees many hours / days (depending on version) of gameplay.

Honest reviews are welcome and thanks for the space.
