I found the block placing mechanic a little difficult at times, but it was a nice concept for a game! I felt that the design of the menus let the game down slightly, as well as the very short looped music.
The concept of the game was excellent though!
Think you should know: game ends @ level 7. Some of the "board" is hidden by the frame. Being off-center means the goal is not seen. Fix for a better score. :)
