It's gorgeous and original, but I confess I did get quite stuck and relied almost entirely on the indicator, as I wasn't quite following how each step progressed to the next (in the sense of cause/effect or my objectives), though I think I started to faintly grasp it toward the end. In some ways this was refreshingly mind-challenging, but I didn't quite get that "Ah that's what I was meant to do" payoff that normally compensates for a click-searcher puzzle.
That said, I do think this was wonderfully inventive and the sound/visuals as components snapped onto the mech were highly satisfying.
