I found it tough to do anything past ordering nuggets, because even after ordering them, I didn't see any indication that the nuggets came/my hunger filling after the delivery person showed up. Besides that, sometimes I wasn't able to buy things even if I had more than enough money to buy the items.
I don't know if I'm missing anything or any instructions to properly play the game, but as it stands, I found it difficult to continue past the early game.
Keep making awesome stuff!
