I love the concept here! The art is super clean, too, really fits the modern delivery app aesthetic. I think all it needs is some better balancing for this to be turned into a full game. Although one idea is to maybe add to the time management aspect by forcing the player to multitask. For example, maybe the price checker takes 10 seconds to check the price and in the meantime the player can start working on another package. One bug I noticed (at least in the browser version) is that, even if an item isn't visible, the player can still pick it up by using the right keyboard shortcut.
