All for Knot!

You either cut your ties, or cut your losses.

This is a remake and expanded/optimised version of facade by Stract and RedSilencer, which in turn is an advanced remix of Abyss by Jotta.
RedSilencer and I collaborated on this remake. You can find his version here.
That's not all, though; a substantial amount of advice was given by the following people, whether it was tips on design choices, or general playtesting:
Narkodes (HUGE thanks in particular - Narkodes gave excessive help with connection optimisation, logic reworks, and provided several of the UCPs present in this map. Without him, this puzzle would not have seen the light of day.)
Mattchew (special thanks for making the thumbnail!)
Didokiller
Teo
Aneonen

You can find the Knot collection here.

Notes:
- the portal inline rule applies: the half voxel portal surface on the floor will only accept portal shots if you are standing in line with it
- no bunnyhopping, a/d spamming, or strafing of any kind. all of these can break the puzzle due to timed restrictions
- jumping off of stacked cubes for extra height to make awkward jumps is NOT intended

Difficulty: Hard
