Great aesthetics, love the dawn/twilight parallax, the chill music and short initial intro which made want to help the little robot!
I got stuck on a puzzle fairly quickly, the one after the checkpoint of the second level. I think the elements you are meant to interact with, and what they actually activate, could use some emphasis or clarity.
I still enjoyed it very much while it lasted though, I love the idea the robots halfs that can do things the whole robot can't and vice versa, there's a lot of potential for more here I think!
Great stuff!
