Your fourth challeng is to play this totally not unbalanced and impossible idle clicker game that I made like six years ago (reskinned to integrate Twenty today but otherwise unaltered) (nevermind I changed some numbers what was I even thinking with some of these formulas)
(There is no end to this challenge. You are stuck here forever. MWUHAHAHAHAHA) As you can see, no matter how you try it takes eons to make a profit from the investment you put into the button. Don't gamble, kids.
