Hello, I haven’t posted in a while. Lol.
I started the TAS of this level around May of 2019, but kept finding new optimizations and tricks, which prevented me from ever finishing it. This stage is massively more complicated than other Amy levels. I was never happy with how my tests would turn out- Even this video has room for improvement, mostly towards the ending, but this is so much faster than the previous record, with so many new improvements, it just begs to be uploaded now.

As for new tricks in this run:
The left-side door clip at the start seems to just be a matter of having a high enough velocity, which is achieved by hammer jumping forwards off the sloped collision.

The Zero Hop out of bounds seems to work for the same reason that the elevator clip works at the very beginning. If Amy’s V speed is negative, she can clip upwards through some ceilings. In the case of the elevator, she is falling slower than the elevator car is, and so phases relatively upwards through it. In the case of the Zero Hop clip, Amy is being pushed upwards by Zero, but her velocity follows it’s normal function and goes negative at the apex of the jump. You have to balance very precisely ontop of Zero to not slip off.

It appears that, In order to make my life more interesting, the SADX Gods left an unused water current trigger around the out of bounds room above the normal stage(?). I can use this water current trigger to farm speed and run around the collision. So, just to clarify, that massive speed boost was a result of weird unique triggers, and not something that can be done anywhere else. It wasn’t some new glitch.

In act 2, I discovered a method to wallrun throughout the cylindrical room via a very precise hammer jump with skewed gravity, to snap onto the wall. The collision around this room is quite wonky, and, despite having fairly high speeds, Amy physically moves slowly across some spots. There doesn’t seem to be anything which can be done to prevent this.

The puzzle room skip has been known for ~half a year now, but it was found in the process of making this TAS. By using 2 precisely spaced blocks, you can clip out and around the back wall of the puzzle room.

At the end of the TAS, in the final tunnel before the end, I wallrun on collision angled beyond 90 degrees. On this type of angle, Amy can run much faster.

Also, now every single Amy level has a wallrun that saves time. Hahaha this game never gets old.

And yes, I ended on a funnee time. I could improve the ending more, but that would ruin it. Someday, when I make the Amy Story TAS, I will get an end time of 1:22.xx or lower. For now, this is funnee.
