You’re still playing in the Mario tile set so this isn’t a Zelda-maker mode but it’s definitely a game changer since you can play so differently.
Another big addition is Ninji speedruns. These are Nintendo-made speedrun courses where other players’ runs appear as Ninji. These have a weekly reset timer.
Other changes include the pokey and spike enemies, as well as p-blocks, dash blocks, frozen coins, and snowballs.
However, one feature missing from the list is the Super Mario Bros. 2 mode. This has been theorized as coming for quite some time now, and if you’ve seen previous discussion about the game here, it’s something that we’re definitely into.
They have as much time as they want to make this and add it to the game, but it likely doesn’t make sense for them to add it once the game’s popularity begins to wane, so many (myself included) were thinking it would probably come out with the first big update.
I think it’s still coming though. You gotta believe!
