I beat this TAS here: https://scratch.mit.edu/projects/454928842/ Sadly, Scratch is very inconsistent, so I kinda had to "cheat" with the TAS -- everything here was played without teleportation or fly hacks or something, but because Scratch couldn't work with just saved and replayed inputs, I had to replay the states as well...
I beat this TAS here: https://scratch.mit.edu/projects/454928842/ 42.8 seconds (IGT), 535 rerecords (honestly expected >1000) The beginning was really bad, but I got box skip, so I guess that and a bus strat variation pulled off the time save. I'll beat you some time, @SpeedrunManiac
