Suggestions for improvement
1. The warehouse restocking employee should only restock items where there are already items in the inventory. Otherwise, they block free spaces for items that aren't yet in the store. This happened to me, and I then had no chance to rearrange them, as the crates were thrown away at the same time—which is actually a good thing.
2. This brings me to the point that it would be good to be able to buy empty crates or retrieve them from the trash so that you can reorganize.
3. It would simplify the game if the items were displayed when I hovered over them with my mouse. Especially with the crates. I have to pick up each crate individually to find out what product is inside.
4. The thought bubble for customers when something is missing or too expensive. The graphics often look very similar, so I can't tell which item is being discussed. Either spell it out or display it when I hover over the bubble.
