Tsuta Intro Cutscene Skip
After entering Tsuta Ruins for the first time, there is no immediate intro cutscene, unlike most areas. Instead, the cutscene's trigger is set further into the main room of floor 1. Because this cutscene starts with a particularly long unskippable camera pan (over 18 seconds), it is very helpful to skip it.
In NG+, after entering the dungeon, one can immediately KT up to floor 2 through the Rejuvenate-able bridge. This brings Ammy almost directly to the triple Devil Gate room, skipping most of the dungeon.
Because in NG+ Spider Queen is skipped, you have to leave the dungeon through the entrance again. This is done by doing one KT over the trigger. This used to be called Chrono Skip, after an old runner called Chrono23.
In NG, the cutscene is skipped by doing a wall-jump on the right-most wall, ahead of the trigger. It is then possible to just clear the trigger by doing an air-tackle over the large vine/root that separates the entrance from the main room.
