You can buy hidden upgrades because someone didn't label the prices properly. (A lot of them you can buy for 10x cheaper than its price.. if you can see the price.) You don't even know what you need to prestige, there's no warning and if your curiosity got to you too early, you're practically reset. In fact, I'm not even sure what the hell prestige does because buying the last upgrade and having 10m does nothing. The UI is so hideous that I'd rather see paint dry. The balancing is so whack that you can finish the entire game within 5 minutes if you know how the hidden upgrades work (most of them are either 2x or 5x their old value except the first 3 or 4 that's 10x) but hey, that's "born wealthy", right?
If this is a joke game, this is it. A joke game you shouldn't play. If I'm missing something, "there are no instructions, just like life. You can figure it out."
