I have no idea what this would look like or how to implement this, but it would be really awesome if you could somehow find the maps you have played before.
Sooooo many times I beat REALLY cool maps and Im like "#########, I wish I could show my friend this one!" Or "come back here with my friend and do this base together!" Or "Haha, cant believe I fell for that! I wanna see my friend try this one!"
Idk, yeah, just would love something thaglt could address those vibes
