I started playing this game recently, and I genuinely fell in love with the amount of customization it has, so I started a challenge zoo on medium, put a few vendors, 7 exhibits with donation bins and info tablets, I basically added everything I could add to boost guests' happiness, but my cash flow is always negative, I tried firing most of the staff, selling exhibit animals, but I can't seem to get out of the negative numbers. What should I do?
