Modified version to use with planning speedruns, with some pointless, bonus changes to make it super obviously not the actual game. May have to run a few times to get the TAS to play properly.
press 1 to record input, O and P to scrub, M to jump to a frame, N+0 to reset the recorded keys, and I to toggle sliders. It has some syncing issues, so you may have to work around that. This run can definitely be improved, there's 6 frames of waiting before the second lift, and another 2 frames when you reach it the second time. Sub 51 is totally doable.. for a TAS, at least.
