Update 2

Graphics update: more walls, lanes at the bottom, rotating partitions between them.

Current goal of the game is to land red boxes in the red lane, green boxes in the green lane and blue boxes in.. well, you'll probably guess it. If you land the right box in the right lane, it's good. If you mismatch it and land it in the wrong lane, it's bad. Grey and beige boxes are neutral, they will just disappear; however you can no longer destroy grey boxes by clicking/tapping them. I'm going to get some sleep now and continue in the morning. You can restart the game by pressing R and toggle full screen mode by pressing F.
