The NSMBU levels Nintendo didn't want you to see

New Super Mario Bros. U Deluxe released with... lackluster content, to say the least. Not only did it not add any new courses to the game, it actually removed some... or so it seems. Internally, the game actually features entirely new worlds worth of unused courses, likely from the original development cycle of the game, that somehow resurfaced during the process of porting the game.

This video is the first part of a series where I will play through these levels with @TCAtrevor, and possibly more guests to come in the future!!

YouTube recognises the game as NSMBU Deluxe but uses the Super Mario Party boxart 🤣

[yeetlejuice]

i love how a lot of this is just clearly the developers messing around and having fun, like all the rotating cubes and the level with silly stone eye placements and the level with the koopas appearing and disappearing in time with the music

It’s intriguing to see so many neat level ideas/concepts/visuals that were scrapped for the sake of the game’s simplicity. With Super Mario Bros Wonder raising the bar for 2D Mario levels, it gives me faith that such ideas will be implemented more often and given the chance to realize their full potential.

30:55 Best part of the video right here

33:44 Entering a unfinished pipe for no reason crashes Super Mario.

The fact nsmbu deluxe outsold mario maker 2 will never make sense to me

[KoffeeB]

Love how they coordinated so well that they get extra distance over the poison

[SaturnRabbit]

9:09 That winding down 'Bah-Bah' tho

@bunshine wasn't kidding about the cozy vibes of these videos. I love binge watching these, and you guys are quite giggly. Also, I'm scared of cheep chomps, they're my worst nightmare.

I had no clue these extra unused worlds were a thing, wow! I really like the way you covered them, great video! :)

[brobeckskazooremixes]

Mkwcat is the best YouTuber, she will take on the algorithm by storm

[jibbygaming]

14:28 This is actually used in super mario wonder!

[yolomationanimation]

Those parallax scrolling cubes are so cool and I wish they incorporated them somehow in some cog steampunky kinda stage, real unfortunate cut character. I’ll miss you, cool parallax spiraling cube

3:52 "we get a star coinnn... ✨🥰💅✨"

You...can't...EAT...ghosts!
Eee hee hee!

[chairwastakengd]

36:43 this transition would be clean if not for the slight shift of the level

[thyavenger]

That Koopa Pipe entourage was beautiful. I can only imagine how many hours were wasted getting it just right… only for it to never be used.

It's kind of crazy that Nintendo predicted the whole Mario Maker '3 bro lives' thing with W40-6 Area 2.

[SergeantCrwhips]

Aaaah, they sound like 2 roommates who play together. god i love this channel, theyre so wholesome (i mean, listen to them giggle at each other: 23:51 )
