Just saw this for the first time, wasn't sure if anyone else had seen it, thought I'd share here. Looks really cool!
yoooooo, okay, so I've been watching this and I saw that the tas does some of the slip locks different.
I tried a couple times for the Royal Tower level, but could never make it past the last lock.
London Subway has to do a full down and then back up, so it's not any faster than our way.
Trying it out on Golden City, I actually managed to do it a couple times. It's definitely possible by hand, but the problem is (at least for me) that mashing hard enough to get it doesn't give you enough time to correct yourself if you fail it. So it's either success or time loss. Not sure if it's worth.
I am now seeing that cupps and vedro helped with this so I'm probably the only one who hasn't seen this lmfao
