itch.io

I guess you're right that many of these all control a kind of metadata. What I specifically wanted to do was change how link previews for the user  appear. For individual games that's controlled under a widget that handles a bunch of metadata stuff (including a tab literally called "metadata") but there doesn't seem to be an equivalent for the user page.

If you can see a setting on here that says "metadata" I would love to know where it is. itch support has not yet responded to my emails haha.

This topic is one of the top results when googling "itch.io metadata" so I'd say it's at least worth consideration lol. Also, same goes for setting metadata for the profile page (which I actually still don't know how to do)

Glad you liked it overall! To succinctly answer your questions in order, since there really isn't anything more to it:

No

Yes

A really fun short game! You can explain it, play a session of it, and learn the meaning of friendship all in about an hour if you want to!
