Great game, money is a little hard to get sometimes, but 100%ing a game like this one is always fun, especially when nearly all of the achievements require luck in some way. "BUFFED OUT" could even be counted here because of the random money rates.
PRO TIP FOR BEGINNERS: Get the gummy upgrades faster than the Bison upgrades because most gummy upgrades allow you to go higher into the sky, and if you pass the sky, you can farm money really easily leading into the Bison upgrades.
