I have 3 levels I'm working on but I was waiting for the update before I upload because I want to test them with and without checkpoints.  BUT...LOL... I had this random idea and ended up making a tiny bite size level with it just because. :) Feel free to try it.  But yes... for the most part, I am waiting.  I will also be fixing / reuploading a couple of levels with checkpoints then as well.

Bite sized level below.

Mario, Like a Moth to the Flame! C4FC-0000-00D1-9DBE

878F-0000-00D2-945F 
Titled: Reset

I tried to make an interesting level without making it too difficult.  I was thinking about waiting for check points, but I think I'll just add to this level later when they become available. 

Expanded the simple idea into a 30 second challenge which 99% will quit. LOL. and renamed it to No Weapons Allowed - Goomba Mngt

I believe the awaited update just went up.

Update is now live, now go add checkpoints to your levels!

Checkpoints are flag in all skin. Even in Mario World.

Btw do checkpoints float? 

That won´t be a issue you can only add two

I re-uploaded my hard/long levels. Now they have checkpoints, so they're more doable or less frustrating... I hope so. Hurry! = B5AD-0000-00D6-B3AE | Doors and doors to nowhere = 7A65-0000-00D6-B774

I'll try to download the update as soon as possible. Many of my levels will be decent with checkpoints.

I just beat Bowser's Puzzle Dungeon (official makers, Bowser). That's one though level, it currently has a 0.87% clear rate. You guys should definitely try it out.
