Donut amount and level up cost need decimal places in the mantissa of scientific notation; scientific notation is pretty unusable early game without that. Not far enough into the game to see if other amounts need the same treatment, but you should probably do a pass over everything
Thank you for the feedback, and you are totally right. This has been fixed. I'm working on the balance issues that came from changing the delivery tiers you mentioned in your other comment and then will get the new package uploaded. Deliveries are supposed to be fun and interactive, as well as one of the primary sources of income for the shop phase, and I was able to verify it could very easily become broken.
