Maybe it's nostalgia, but I loved the setting, It seems like you went to great lengths to create the atmosphere of a supermarket (from a kid's perspective) with the ambient sound and texturing. And this is totally the kind of game that a bored kid dreams up on a dull shopping trip with mom and dad.
Based on the previous comments, it seems like you're aware of some of the gameplay jank - but once I figured out the "shift-to-stop" trick, this was a quick, breezy, fun entry. Nice work!
