Actually managed to get whitelisted for Geometry Dash custom level use...
Although I already tried that probably before even 2.1 release
Years have passed, I probably only had like 3 musics completed, with only 1 published. Now I have 20 completed, with only 12 published
Back then, you had to get RobTop himself to whitelist, so I immediately gave up and never bothered to do that.
Until roughly 1-2 years ago when I heard that you can get whitelisted through elder mods instead and attempted again.
Of course they'd be overwhelmed with hundreds of replies, so after DMing literally every elder mods once, and then the second time several weeks after, I gave up again and DM'd every elder mods again when 2.2 teaser appeared in my recommended (that was few months ago)
Yeah, no luck, but then I noticed that one of the elder mods (Hado), created a google form and spreadsheet in order to keep track of everything. The use of google form was an excellent choice, I only had to submit the form and wait, that's it
And finally whitelisted after years, and even better that it happened before 2.2 release
Well but idk, I don't think I'd return to GD even after 2.2 release, I already have another game to enjoy
