Press SPACE to save data, the project won't work if the Bot's offline, so instead, it will prompt you to copy the save code instead.
In order for your Save Data to Sync, you HAVE to be a Scratcher, not a New Scratcher, so you may want to upload a few projects before you get the link to upgrade, and after then, you should be able to use this! Server-hosting questions, and how you can use them in YOUR projects can be found here! https://scratch.mit.edu/projects/1064056747 Made by: @SlickSquid3701
