nice game . Some suggestions from my side, first as soon as the tile hit the ground give feedback because I was using down key to bring it to correct place but still I had to wait, breaking my flow. Another thing is that the projection you show at the bottom sometimes is more of a hinderance than of use. This combined with the background didn't allowed my to distinguish between previously placed and not placed tiles. Hopefully this will help you improve the game further. Good Luck!
