On even further examination of the balance, I keep getting balance problems similar to that of my first comment throughout various stages of the game. After a certain amount of purchases, the balance switches back to something logical, then becomes deranged again over time, before switching to a logical balance. I'm yet to determine the exact pattern of these changes.
On my previous comment, the balance seemingly fixed itself after a while. Many of the exaggerated figures dropped. I'm assuming it was some sort of bug. Glad I took screenshots though.
I wish I could post an image to show how super confusing the balance in this game is.
The following is a list of how many of each item I have and the cost to buy another 1 of the same type next to it.
571 Lemonade - 224.291 quadrillion
300 newspaper - 97.163 quintillion
291 car wash - 26.1 quintillion
291 pizza - 24.117 quintillion
270 donut - 2.016 quintillion
270 shrimp - 2.148 quintillion
270 hockey - 2.015 quintillion
270 movie - 2.054 quintillion
270 banks - 2.046 quintillion
301 oil - 16.231 quintillion
The last 4 all cost 10% less because of angels, so it's understandable why the shrimp and hockey prices look weird. But what I don't understand is why the hockey, movie and bank prices are so close together (also the bank costs /less/ than the movie). Nor why the newspaper one is 6 times the cost of the oil one. Nor why the next car wash costs /more/ than the pizza place.
