By clinging to and unclinging from the left wall in the previous room, you can dash left once and then dash right to your heart's content with wall cling storage.
Without dashmaster:
- If the glimback is on the right, wall jump over it midair and continue as normal to save around 0.4
- If the glimback is on left, you can either do the same thing or go for the chain and do the sequence in the first video to save 1.1
With dashmaster:
- If the glimback is on the right, do the sequence shown in the second video - delaying the dash after the glimback pogo helps make the rest more lenient but make sure not to touch the ceiling
- If the glimback is on the left, do the sequence shown in the third video - the background object on the left is pogoable but the right one isn't so dash quickly after pogoing the glimback to line yourself up
- For both patterns you save around a second, and if you lose too much height and have to midair wall jump you barely lose anything to a perfect room.
- Theoretically you could probably save more time by chaining and keep wcs through the entire horizontal section of the room but it's pretty hard because you can graze the wall
