I concur with much of what has already been said. The little robot had a distinct personality and this was granted him simply through the imaginative atmosphere, theme and curiously attractive art style.
I agree that there is this kind of feeling like the things you do find, are subtle instructions and it was also my assumption that there was a trail to follow, that somehow there were connections between what I was seeing and where I was supposed to go.
I would really encourage you to keep working on this one. I really think you have a great premise that begs to evolve.
