We had datastores

YESSS! We have datastores. Works through HTTP in Firebase without the DataStoreService api.

Tutorial is by some user and not by me in the devforum, i want to not have a waste of time explaining.

https://www.mediafire.com/folder/l3pi7s4v0xdzp/DATASTORE (Download one of one of the 3 files in mediafire in this folder, because the free plan doenst allow multiple downloads.) You can read the docx file to learn more, the tutorial is not written by me. Note: At the end of file you find "Firebase.UpdateFields("users","Test1",datatoupdate)", for example is in my datastore, you need to replace "Firebase.UpdateFields" with "FireStoreService.UpdateFields" at the end of script (without "")

Scripts are in the folder of game file.
