Found two glitches in this game that should be useful in the run.

One is, if you jump and attack, there's one specific frame where you can jump after the attack animation is done, if you chain these up you can gain height indefinitely. You need to chain a few to get anywhere tho so probably not useful, being so precise.

Second one is a way to clip through those force field walls, basically, those walls don't hurt you if you look in the opposite direction, so if you jump into them and look back, then let your momentum carry you through, you just phase through them. Clipping fully through is kind of precise, but its easy if all you need is going in and out, like on the one surrounding the Vault morph.

I'm trying to TAS this game, so if anything else comes up I'll share it here.

Some more stuff I found.

Found a way to clip by moving into those orange robot enemies when on a higher platform, the kind of height you can jump with the basic jump. This just makes you fall off the floor and into the void, but you wrap around after a bit and appear at the top, and the fall damage can be cancelled with an attack. Maybe there's some case where this can be useful as a way to get to a higher platform, but it takes a while so you'd have to be skipping a lot for it to be worth it.

The Leap morph can be used to move faster, its not a lot faster, maybe you save about 20 frames each leap, but it is faster. The leap can also be extended a bit by attacking near the end of the leap, and makes it slightly faster.

When you do a cutscene override, you can jump at the next frame, even when midair, this could be useful in some cases.

Tho the leap can be extended by attacking, its still slightly faster to just spam leap, unless the extra distance lines up better with where you are going.

The cooldown of the charge morph can be cancelled by just pressing l, which makes it possible to spam charge and move way faster.

To do the cutscene override, you don't actually need to time it, just by holding l it happens, tho you won't be able to move until you stop pressing l.
