Absolutely awesome. I found myself thinking, 'oh yeah, I get it' on the first level, but was compelled to play through the whole thing. It just made me want to finish it. The neat puzzles, figuring out how each button changed the environment, the chill music. All great!
I did manage to make the poor robot jump to their deaths a couple times when I made them get too close to the red boxes, but it was more funny than anything because resetting was really quick. Also, in one puzzle, was the real solution to hit the button and then quickly order the robot across before the platform dissolved fully? Because I did it, but I'm wondering now if I missed something.
Awesome game and I'd love to see a full version!
