Hello! I looked around and couldnt find anything recent.
I want to keep and maybe display the current high score of my game from everyone that has played.
Is that currently possible on here or no way yet?
Do they need to log into somewhere to do it?
Basically I just want them to input their name, play the game and save their score.
Any help is appreciated!

No, itch.io doesn't offer such a feature, and there are no plans to do it. Sorry.

I ended up having to get my own server and making a mechanism for it. I made it quite universal, just need a unique game name, and your code to send it to the server, and then load it from the server. It's also a good factor for comparing downloads to people who actually play the game... assuming the players are actually online.
