I. Get just under Infinty cookies.
Note: having Infinity cookies will bug the game.
Game.Earn(9e+302);
II. Buy 1000 of everything.
Note: all prices start to approach Infinity with counts nearing the upper 4000s.
Game.storeBulkButton(4);
for (let i = 0; i <= 14; i++)
for (let j = 0; j < 10; j++)
document.querySelector(`#product${i}`).click();
III. Buy all available upgrades:
document.querySelectorAll('#upgrades .upgrade.enabled').forEach(node => node.click());
