Generally nice game.
I was playing to get exact number required for next bar. And I encountered a bug at 10^27. Visually I've 10^27 / 10^27 so I should get new elements, but I didn't. It's probably because you are using floating points and there is some error in underlying value caused by loss of precision. If you would like to solve it you should probably look at some big numbers library.
Best regards
