The game is good but needs seperate levels to work even better, because right now you just try to get as many slots as possible then buy the most expensive thing in the shop and just deliver that to get the most amount of money. A better way is to have levels which have certain upgrades/foods unlock and mainly used in that level. And after introducing the new foods, the levels get more complicated. And the shop/upgrade part would be between levels to have some time to think about what you want to get. Then the game would have more structure because right now it's more of a sandbox feel.
