There seems to be some partial misinformation as to what exactly happens while executing the death clipping glitch. As you all know, it requires you to have a minimum distance between a checkpoint and a ceiling. As I've found in my understanding and experimentation, contrary to what some may think, there is no mashing that is required to execute the glitch. Instead, what determines if the clipping happens is actually right as you die. During re-spawn time, whatever buttons you press will be "stored", delaying the input from happening until the re-spawn is complete. This "storing" action happens in many places where there is a delay. Such occurrences include: At the start of the game, while you pick up an item, and in this case: beyond death. With this knowledge in-hand, it's determined that all is required of input during re-spawn is that you do a back-flip. Simply press both left and right buttons at the same time (to do a stand-still backflip), then press the direction you wish to move when you re-spawn.

Feel to ask any questions if something wasn't clear, I hope this helps you guys.

TL;DR: No mashing is required when doing the death clip glitch. All you need to do is time the first back-flip correctly, back-flip in death with left/right pressed, then hold a direction or none at all.

Yesterday I noticed that I was doing backflips wrong, I didn't know that you could do it pressing both left & right buttons + jump at the same time, lol. So yeah, my way of doing the glitch is wrong, you don't need any walls near to do the glitch. You don't actually even need backflip to do the glitch, but it's necessary for giving you enough height for doing the glitch on most places. I still argue that my technique is little bit easier on places where there's enemies, but not when you're doing it from spikes.

I'm gonna update my guide someday. At least I'm gonna put notice on top of the guide for new players temporarily until my guiden has been updated.

How did you pull off the glitch without using a wall? I've never managed to do this in a long time of testing.

Essentially all I was saying is that you don't need to mash to do the glitch. I understand that the only hard part is doing the death.

Also, when you say: "You don't actually even need backflip to do the glitch", were you referring to the death part of the glitch or the entire clipping part included?

Maybe I was wrong about not using the wall, it doesn't seem to work after all...

Entire glitch, here's how to do it without flip, but it's not that useful: https://vid.me/PijF

Ah, I see what you mean. Thought you were talking about the spots where they're used in the any% route (those require a backflip)... It seems to only work in places where there's a ceiling of that height at maximum. Thing is, you only need to get the spike + jump combination for it to work. After you die there isn't any more need to input anything else, as a successful death will always prevail.
