I don't think they've announced any phone app plans, but I wouldn't be surprised if it happened
If not didn't fans create their own website for that type of thing for Mario Maker 1. I'm sure they'd do it again for 2.
No. There was an official one. And it was much easier to find and share levels. You could bookmark a level on the site, then go on the game it it would be right there in your bookmarks. No entering in the codes and shit.
Was that there right away though? I thought it wasn't added until sometime later.
Edit: Just looked it up and it appears the bookmark site was launched in December, about three months after the game released.
That's cool but like, they should have known better for the sequel you'd think. ---
