Door shell X-mode setups and applications

[blkerby]

There is a trick in 14% xAmmo that gets X-mode after a door transition from Main Street into Everest, and uses it to cross the room: https://www.twitch.tv/kingofthehill476/v/457656761?sr=a&t=1602s. Bobbob described some kind of normalized setup here: https://vimeo.com/746657523.

It could be worth investigating if there are setups in other rooms (with or without water?). I imagine there would be many other rooms where being able to cross the room like this would be useful. If the starting room is air, maybe you could do it with dash speed and be able to charge a shinespark this way? Haven't looked into it, so no idea what's possible or not.
