Oh wow, thank you so much for such a detailed and well thought out response! Comments like these make itch such a valuable resource for indies.
As it was a 7 day game jam, I didn't really add any kind of end game. It's just meant to be a short, calm, easy, relaxing game. The money is produced every tick (day), so it happens constantly.
Great idea about the pack, that would have made the UI so much better. Wish I'd thought of it. Thanks so much.
