Alternatively, when the size number approaches the upper limit, store the result in a string of characters instead of the numeric memory type. For example, you used prefixes for the word "meter". A numeric variable can go from 0 to 999.9, then changing the prefixes or adding new ones. Or by adding zeros at the end, as you did in the previous game. You can do the same with graphics, that is, you can separate the rendering from the values, simulating the growth rate based on actual numerical variables, while text variables carry information about the degree of enormity of the size.
