For the upgrade menu, just move purchased upgrades to the bottom of the queue. Also, maybe to prevent loss of money to do rounding glitches when the cycle gets insanely fast, perhaps just cap the speed at one second, then just increase the amount of money gained per cycle after that point.
Fairly satisfying 2 hour run. Please....check when you use apostrophes. They are used when you need a possessive form of a word, not a plural. For Example - The planet had three moons. (correct plural); The Planet had three moon's. (incorrect plural); The moon's light reflected off of the lake. (correct possessive); The moons light reflected off of the lake. (incorrect possessive - unless you meant for it to be plural possessive, which would be moons'.)
