I am trying to make a saving system for the eggs they collect. I have a script that inserts boolvalues with the eggs name but I don't know how to make it save the boolvalues. (I am not very good at scripting) Also I am scripting the game before I start to build the game. Link to the game: https://www.roblox.com/games/6440950983/Egg-Hunt
You would need to use Datastore service. I can not help you much, as you have not attempted any code.
Here is a link to the Roblox devForum, with a Datastore Tutorial. Make sure to read it so you understand :)
