||DUI is a world full of blocks. To pass the level, you should remove required amount of blocks and get the left blocks stay inactive(NOT ON GRAY BLOCK).
Furthermore, we strongly recommend that you get your hands wet with the level editor through which you can create your own blocks world and then share the levels you made with your friends.
DUI took us two months to bring it to reality from scratch. Although it’s far more from perfect, hopefully you all like it and thanks a lot for your play and comments. :)
