So I figured someone better post a thread so we can all share each other's sadistic levels with one another! What's great is you can follow a creator so we can know when NA members make new levels.

Here's my first level: The Evil Underground
C988-0000-0016-3D59

I don't know if I'm rusty or what but this level took me a really long time to beat.

Levels are in the third post!

I believe I can fly!

29A6-0000-0012-665C
Mario Goes to White Castle
1399-0000-0012-DAC3
Green Leaves (Are Made of This)
2AE5-0000-0013-BF25

LEVEL LIST BY MEMBER:

Rules:
3. We suggest but it is not mandatory that you provide a difficulty rating of your level ranging from Easy-Medium-Hard.
1. If you edit(re-upload) a level and or remove a level please PM me and I will remove/update it from the list.
2. If you edit your original post to include new levels these will not be added unless PM'D.
4. Don't be a level crapper!

On a side note I am doing this on my free time and it will not be perfect but as far as I know this will probably be the best way to keep a list.

I'm looking forward to downloading these levels and trying 'em out!

Baaaaah! Can't wait to get off of work and crank out some levels!

For me I'm going to create levels that are complex and require skill, but aren't impossible. I love having alternate ways to go through a level and my first one definitely has ways you can be stylish. 

 

Definitely going to check this one out tonight.
 

Ya that is what I mean, the fact you have to be able to beat your own level is awesome. Hopefully I can get one whipped up tonight for everyone to try.
 

I'm going to check this thread constantly and play everyone's levels. Also you can follow a creator's levels so I'll be doing that too.

Random Painful Things (my first stage and not very hard but with a few hard elements)
8348-0000-0015-D12D

I'm actually kind of tempted to buy this....

Just played it SJ!  Nice job  Took me a few tries, but I got through it.
 

This is so cool. I guess I have to buy it now.

Thanks Quack, I appreciate it.  Going to try making a castle type stage next.

You mean it was up for debate before?

Nice. I will try it when I get home. Anyone beat mine yet?

Haven't beaten yours yet Sub or any from Cheese either. You guys are kinda evil you know

Just made my first one, pretty basic so far

CDCC-0000-0018-E738

Let me know your thoughts/feedback!

I created one with extremely limited smb 1 resources. Ill post it soon.

Fuck you and your level Subcon!

I was thinking the same thing about your level Quack! Damn you!

Haha! Just beat yours. I seriously almost beat it the third time and died at the flag!

Fun level!

My first go. 691B 0000 0019 9DEF

I found it quite tough...

Edited because I edited the course

Nice board Geoff!
