I like how fast the character moves to get around the store. It was difficult to keep track of where the character was going as the camera wasn't able to keep up. A potential improvement could be to zoom the camera out and show more of the surrounding area.
I like that the colour scheme for the items help them standout from the background elements. When collecting the items, it would be nice if there were some sound effects on the item collected, and an item counter to know how many items are left to collect.
