Cool! I dig the vibe created by the art and audio a lot. Really gives the feel like I've gotta take care of this cute, little dude.
I agree that the controls often felt a bit weird. And at one point I got stuck in the vending machine screen (?), and while I was in there the little thanks for playing thing popped up, so that was pretty unfortunate because I felt like I missed the game and didn't really understand how I had progressed.
I would say that this is one of those entries that would really benefit from being expanded on, if you feel like it, of course. As is, it's definitely a neat little demo with lots of potential!
