This is an even one, that supports up to around 100 GOOGOL!!! and uses way less blocks! there might be a little error after a quadrillion... that is a rounding error in scratch or something... i cannot fix that... :/ press space to make it multiply the number by 10!
LXtricityGames made the original! i saw that Bafity made something very similar, i only noticed that after i made this! go look at both of these people's work, and maybe even follow them!
