Super Mario World glitches. Mmm. Tasty.

Someone made a custom Super Mario World level just to show off all the glitches in the game and this is it.

While all the bugs presented like this is totally cool, I would like to take a moment to ask: does the idea of someone designing a custom made game level bring out the inner game designer wanna-be in anyone else?

I would love to design games. Yum.

Anyway, remembering back to my game console days, I knew about the key glitch, but I had no idea there were so many others. Someone try them out and tell me if you got them to work!
