This was well cool! - i especially loved the addition of ramps and the breaking glass
a couple of nitpicks:
the camera seems to zoom in after parenting quite a few items to the shopping trolley (around £41 worth)
i think the shopping trolley begins moving on its own aswell after that price
also i think it would be great if the other shoppers moved along and collected stuff and you could ram into them to steal their shopping
but even without all this it is a great game! good job!
