I had a lot of trouble with the part with the fire part. It really was a pain in the ass.

I changed the download hosting site. I'm pretty sure that the file is a .smbl.

[2ND EDIT:]

Well, I tried dabbling with the original devmode before, but found it to be a little intimidating. Then just yesterday I unlocked Super Meat World (I'm not a total noob, the computer I started playing SMB on died, so I had to restart). Holy crap, all those levels are challenging! After that experience, I decided to make my own level Here it is.

EDIT: I updated the level's looks a little, and have determined that a reasonable A+ time would be in the range of 21 seconds or under.
2ND EDIT: Well, I updated it again. It looks cooler.

Sorry, the screens aren't that great. Please tell me what you think of my level.
