Anyways...
I'm Catpan (or Corndog52), and I love SMBX. I've been screwing around in the level editor for quite some time now before I actually decided that I would start working on an episode. Completing it is a whole different ball game that I might not even participate in, but I'll surely consider it. I've already made two levels for Super Mario Reboot, but one's just a battle mode rendition of the other with a few minor changes.
To download either level, go to http://www.smwcentral.net/?p=files&u=28815 and use CTRL+F to find either "SMBR-1" or "SMBRB". Once you've found the correct level, download it. (Kudos to Jayce 777 for getting the image to show up without me having to give you a link!)

Check out my first level, CompanionBound: http://www.smbxgame.com/forums/v ... hp?t=14888
I have not made a single 1.4 level yet, despite what I've put in my posts' titles by mistake. Most of my levels are vanilla 1.3.0.1, as I've not gotten any SMBX builds in a while.
