Maybe you could make it so you can set it to show stuff like 69*10^18, 6.9e+19, or 69 quintillon? (It's thousand, million, billion, trillion, quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, and then you could do like kilodecillion meaning undecillion, megadecillion meaning duodecillion, etc. etc.)
Does this ever wrap around? If not, make that, but make it a bit harder by making it so that if you don't click, you lose some gold (depending on level and upgrade).
You should make a sequel that's more high-quality. Shrink the size of what you'd normally have so you can see it, make fewer decimal places for the e+xyz, offline bonus, put these abbreviations: K, M, B, T, QD, QN, SX, SP, O, N, D and then the e bit (e.g. 3.14159e+777) and make it so you can change from the es to something like 3.14159 x 10^776. Do as much as you can.
