@twolines: I really like The Ghastly Mansion. I finished it first go, but I keep going back to explore other paths... which have subsequently killed me. :D

That tall room with the ghosts is aces. Just squeaked through on my first run and felt great about it.

I guess I can share a few.

01C4-0000-0018-6BB2: My first course and an attempt a more classic SMB course.

42E6-0000-0026-56EE: Castle in the NSMB style, very difficult.

I've got several more if you browse my profile.

I've made a bunch of spoiler comments, so you can read them if you want to find out where all the secrets are!

(We're talking about B451-0000-0047-9A36, just a bump since it took me 4 hours to make and I want to share the results of all that work!)

First one I've felt comfortable enough to upload. It's hard but not stupidly impossible. Take your time.

Castle Grayskull:

30D7-0000-0048-BE08

Feedback welcome. I don't even have half the stuff unlocked yet, I'll get more adventurous in later stuff.

I've got a more classic-style underwater level that is light-medium difficulty, and pretty fun, I think. Name is "Cannonbill Run" (you can probably guess what the main element of the course is :p)

479B-0000-0044-E488 is the ID, thanks in advance if you check it out. Ill go through some levels in this thread right now.

Part 3

IDK about that guy who posted a Cinnamon level, stealing me world 10 theme... I updated my list last night and forgot to come back and post here so, three levels of medium-hard difficulty.

10-1 Bombomb Cruiser 047F 0000 0044 C540

10-2 Cinnamon Tower 96CD 0000 0047 66CD

10-3 Cinnamon Bridge 65D8 0000 0047 6930

10-4 Cinnamon Fortress (NOT UPLOADED) still only have 10 uploads, thought about making an auto level just to get cheap stars...

@espgaluda: this was really dense. I always appricate the design of these more than the crazy hard ones. anyone can play way too many enemies but it takes some skill to make good design.

plus its not as fun.

good stuff. enjoyed

Don't Stop! Maybe Stop?

A6F6-0000-0048-CFE4

Am I making these too hard?

I tried making a "meat and potatoes" 6 level world set in SM1. Inspired somewhat by Jeff's comments about wanting some Mario-Ass Mario levels.

https://miiverse.nintendo.net/users/KCDinc/posts

Also I find it easier just to post that miiverse link since it auto includes your level uploads and codes.

Here are some of my levels:

Ma-Real Level: 4730-0000-0049-A440

Mario Time: 0A1C-0000-0047-49B8

Goomba Paradise: 846E-0000-0047-OAB9

Need to unlock more things to make better levels, but this game is everything 10 year me wanted from a game!

BC2A-0000-0044-1349

"Find the hidden stars! EVERYWHERE"

This is all about treasure hunting for gear(stars) you need to get through the level. There's a hidden area, a bit of medium difficulty platforming, plus a race against time as your star runs out. Might take a few runs to get through it as you hunt for the stars.

Let me know what you think!

I have a few courses I would like to share as well:

Legend of Zelda: Mario of Time A91B-0000-0047-74E9

This course is very challenging and includes some recognizable set pieces from LoZ: Ocarina of Time. I've also included a "Master Quest/Hardcore" mode where you can try to collect all 99 coins before time runs out.

Mario and the Magical Mirror 184A-0000-003F-A9E5

This course is average difficulty. Mario discovers a giant mirror which transports him to parallel universes. Can he overcome these strange new lands within the mirror's glass?

Mario in Manhattan 718B-0000-003B-2E09

This course has two goombas shagging on a balcony in the big apple. Can Mario survive a night in the city?

https://miiverse.nintendo.net/users/GamerBKL/posts

Bumpin

my first course after getting all the stuff. its a really long maze, it uses all of the main level and sub level.

4E10-0000-0048-247A

and made this one thinking of @danryckert. 0E09-0000-004E-2435

Just put out my newest level, Impasse Pipeline. Man, pipe levels are hard to make well. This one is super Mario 3 Like. It's got that one thing that one Mario 3 level did only with a twist. You'll see. I think it's my prettiest stage yet, very detailed. Lots of pipes going every which way.

376A-0000-004D-7D48

Just made my first three!

Mild Subversion: 4575-0000-004C-B72A

Hops: 24A2-0000-004C-E628

Snake Pit Sine: 5C59-0000-004D-EF53

@frybird I'll check back periodically to see if the sheet is unlocked and add it there too. Thanks!

Here are some IDs for a few of my levels.

First Level: CEF4-0000-001D-4835

The Plumber: 1973-0000-0025-A4D0

Skinny Mario to the Rescue!: 2549-0000-0028-C44A

Speedy Ship: 7CC2-0000-0031-C1C1

You can follow me in Super Mario Maker if you want to see some of my other levels.

Noones beat this one yet, but I really dont think its that hard. Try it out if you want 87FB-0000-004E-1BCF

Hi guys!

This was my first serious attempt at a proper level with a decent difficulty, so try it out and I'd appreciate any feedback!

3320-0000-0050-51D9

I've now hit my 10 limit (it goes to 20 once I get enough stars right?)

My latest is an -almost- single screen experience :

Death From Above : C43A-0000-004C-602F

My fave level that I have made is this :

Door to the Airship : 42BC-0000-003E-9501

It's a (hopefully) nice playable fun airship stage. No Bullsh't, just some nice platforming action with doors.

I'm also really pleased with this one. It's a SMW stage, with a few secrets to find if you take a look around/fall off at the wrong places :)

SMW Secrets and Fun : 2254-0000-003E-9139

But feel free to check out my other levels. Precision Swimming has been getting some love recently ;)

Two more!

"The Unreliable Narrator" -- 9AF8-0000-0051-7CC6

"Abyssal Bliss: Thar Be Gold" -- 8D2B-0000-0051-F295

https://miiverse.nintendo.net/users/Ichimonji/posts

Check out my profile and pick a course!

90FD-0000-0049-6B3B

B57E-0000-0048-547D

"Save the village"

13C3-0000-0053-26B2

2D03 0000 0053 5DC7

This is a large level with a few alternate paths, upper, mid, lower, and underworld.

Medium difficulty. No huge enemy clumps or anything. Plenty of secrets.

Most of my stages are based off of traditional Mario brothers style. Just simple fun. =)

Here is the code to my 1-1 stage. Still working on the rest!

8074-0000-0050-D4BA

Hope ya'll like it! Nothing to hard, but it doesn't play itself ether. Good luck to everyone out there making and playing courses!

Finally added some new stages

3C0D-0000-0052-B2EC is 'Through the Backdoor', a hard SMW Castle stage - currently a completion rate of 6%!

239B-0000-0043-D040 is 'By Mushroom, By Ground, or Yoshi', a Super Mario World stage/

Just uploaded my third level called "Disposable Yoshi Factory", it is medium difficulty, has a fun little gameplay hook, and based on the feelings @Jeff has regarding Yoshi, he would probably be into it :P

Course ID is AA4C-0000-005E-00B9 if anyone is interested!

@sparkysanxion: Just checked out some of your levels, really liked the Airship level, and the swimming was fun too. Managed to finally beat Death from above too :)

Still making levels:

CED4-0000-005D-7B4C Throw Those Shells

My latest stage, Bombin' Buzzy's Boudoir, is out! It's sort of the opposite of my earlier stage March of the Wayward Spiny. Enjoy!

D2D9-0000-0059-22E5

I just uploaded my first stage. It's short, but it's also on the harder side of things and has two potential paths to choose from.

93D5-0000-0059-4D1A "Little Plant Shop of Horrors"

I've uploaded this one recently, nothing special, more of an homage!

Mario Gear Solid - 7564-0000-0043-7D31

WARIO'S GOLD MINE, PART I

94FB-0000-0029-0BE0

Wario's excessive greed has gone too far, he dug to deeply, and now has awoken ancient enemies. Can you escape in time?

MARIO KART MAKER CIRCUIT

8E9F-0000-0059-0139

Go for a fast ride on this Mario Kart track. Watch out for those springy mushroom hops, and slide in over the finish line!

"Runnin' and Jumpin'!"

46E6-0000-0059-C09E

Used my first level "Run, Jump, Duck, Mario" as a template. It's pretty much a more fleshed out remix of that level with different paths, and some little secrets. Try it out! Let me know what you think too!

BLOOPER REEL

F46B-0000-0030-C041

You've stumbled across the remnants of the Blooper Wars, a horrible event that turned blooper against blooper, and left not a few blooper babies orphaned. Will you escape in time, or become another casualty of the uncivil conflict?

THE BEST OFFENSE...

A16B-0000-0045-2C7F

Skip the fire flowers and foot stomps, and see if you have what it takes to infiltrate Bowser's newest fortification. Sometimes the best offense really is a good defense!

7B5B-0000-005A-6679

Here's my second attempt. Let me know what you think

I spent a while this afternoon making a Pikmin themed level (well, as an excuse to fill a level with giant enemies, anyway) and I'm fairly happy with how it turned out. Hope it's fun! 06B1-0000-005B-CE3E

I wish you could make giant bricks/question mark blocks.

Hello again! After some good tips and lots of playing and replaying lots of levels I think I've learned a lot. I feel these three levels are my best efforts. Hope you like them!

Getting a Feel For This (Refelt). 07A0-0000-005C-0EB0

Close Shave n Hot Wax (redone). 5ADC-0000-005B-F0EE

Tight and Hot (rebalanced). 6D12-0000-005B-CD18

Question regarding costumes for Mario. When Jeff played the game on the release day UPF, he mentioned something about how to get the Mega Man costume. I think he said it's tied to an amibo, but there's a way to unlock it for yourself if you didn't buy the amibo? Am I making that up?

I've only been making courses for a few days now, but I really enjoy making short challenge courses.

ADC6-0000-0054-373D Leap?

9248-0000-0057-842F Leap more

8B24-0000-0059-166B Dangerous Parkour

9A38-0000-0059-3051 "No, Ed!"

4A97-0000-0059-5DFD Spring Ninja: Easy

8AB4-0000-0059-6120 Spring Ninja: Hard

6DBD-0000-005D-3F81 Leap further

The only one that's mean/unfair is "Leap more", because it has Lakitus. The rest are beatable with timing/skill.

@lukeweizer: If you complete 100 mario challenge on any difficulty, it unlocks a random skin for SMB1 amiibo mystery mushroom. Just keep playing 100's until you get what amiibos you want.

I found a bug in my level thanks to the death map of other players! Handy, wish I could make it larger, or even watch the replays.

CED4-0000-005D-7B4C Throw Those Shells is now v 2.0

Got it. Thanks!

FYI, Patrick Klepek has been doing a morning Mario Maker stream every day around 9:30 AM Eastern on Twitch. Takes suggestions for levels.

He played my Tower of Joy at the end of this morning's stream!

Archive: https://youtu.be/G8qKB3m6eC0

I remember playing your level and because of your branching paths, Patrick played it differently than me. I used the P block to get to the warp that takes you to the end while Patrick didn't take the shortcut.

Everybody Loves Being Underwater

3B15-0000-005D-A7F5

Here is the first course that I'm happy with, now that I have most of the building items unlocked.

Mind the Gap: 9C71-0000-005D-9CD5

It is a small, not-too-challenging level, but there end up being several different ways to reach the exit (some better hidden than others) so I encourage you to play it more than once. And yes, Yoshicide is one of those options.

Do custom sounds (as in, the ones you record yourself) actually show up in your uploaded levels? I put one in that had custom sound and when I did the play-to-upload bit, it was not present. I wasn't sure if it was something I accidentally did, or if it really doesn't let you upload sounds for others to hear. That is incredibly disappointing if so.
