Got to 100 orders filled! I think I can play indefinitely from here, or at least for a long time - I think the difficulty could be scaled to get harder more quickly. Holding a stack of food and being able to serve from any point in the stack ends up having interesting consequences - I ended up maintaining a huge stack so I could serve new customers quickly. It's also amusing to have such a big stack on top of a small robot, haha. Artistic carpets. Wish there was a trash can to dispose items, especially when my stack was small and I was learning to play the game, but it's also kind of nice not having one.
