Have you ever played a scratch game and found out that you require a save code? Well, in this engine, it uses a cloud variable to store the code for you under your username, so when somebody clicks on the green flag and their username matches the encoded one stored in the cloud variable it triggers a piece of code (your game code.)
How to put this into your game: - swap variables with lists to store multiple items. - hook it up to some save codes. - I reccomend using https://scratch.mit.edu/projects/967671399/ cloud list. Why to put this into your game: - fast - reliable - only 65 blocks - one sprite - no chain credits
