-Press enter to change the number(limit is 10000) -Space to save(I made it intentionally) lengthy to stop cloud spamming -Then refresh the page to see if it saves(doesn't work for new scratchers)
This save can only contain around 350-500 people because the cloud variable limit is only around 10k digits UPDATE: Scratch limited their cloud variable length to 256 digits so now it can only contain around 9 people per cloud variable :c Possible workaround: Every time you work on the project, move the data on the cloud variable to a normal variable then save the game.
