I really love the concept and I wish I could have experienced it. But the controls were just not clicking with my brain. It felt, intuitively, like I could select an object and just move it, and then pressing another number would select another object. But then I couldn't select an object until I pressed Enter (which sometimes even continued after the level restart!) So by the time I figured out what state the game was in, I had usually already run into the thing I was trying to me.
