A wall-jump glitch has been found by @EdgarFigaro . This glitch has potential to cut seconds up to minutes from a normal run, so I decided to separate it into a new subcategory that allows or disallow glitches.

For example, after obtaining the Stasis ability, you can just go left, wall-jump and reach the door; skipping the entire Stasis-tutorial room.

All runs which were submitted before, are now classified as "glitchless" runs.
