I love the idea - you can make some very cool game with it! Also like the graphics, even though it's just pretty much default Unreal Engine graphics. Unfortunately, can't really enjoy the gameplay - it's quite hard to control that dude in air, to jump out of 1x1x1 hole and sometimes there is no possible way to get up. Even though music is original tetris music, which is quite nice touch, it does not really match the graphics.
