Casually browsing on youtube I came across this video:

The glitch he encountered looked interesting, I decided to do a little experimenting. I attempted this many times using the spring pads in PHANTOM Express, it only reproduced for me twice out of the 200+ times I tried it.

In his video he seems to clip through the collision, which was not the case for me, as soon as I touched a wall I shot down to the floor.

Currently it does seem extremely difficult to pull off, and I am still not entirely sure what causes it. More investigation is needed.

Can I request a NG+ Any% category to be added to the main games categories. I plan on attempting a few of these runs soon, and would like somewhere to submit my times.

I think its a unique enough to be one of the main categories (rather than a misc. one). A run without having to worry about the PHANTOM point requirements for levels, so just the fastest completion of all stages.

Done on a save file that already has all levels unlocked/completed. Timing starts on the level select screen, upon selecting Stage 1: Battle For Shell City. All stages must be completed, in order. Timing ends on the last hit to the PHANTOM commander.
