[TAS] SM74 Ten Years After v1.0.1 can be beaten!

In his 1.0.1 update of SM74 Ten Years After, LinCrash locked the first key door leading to the second overworld. However, he had left the metal cap switch in a stage that was placed in that second overworld, making the metal cap unavailable for the first key fight.
FramePerfection conjectured on stream that this route might be possible, which I show to be correct here - sadly, it doesn't look like the pause-BLJ on the Thwomp nor the SBLJ back are remotely viable for Human completions. It is actually possible to reach the alcove with the fire spewer using just a sideflip dive rollout-cancel slidekick, but I didn't find a way to progress any further from there.
