Thanks for the vid, that's interesting. My finale part was totally inverted from this, taking the main body up the fan with a connector rather than a ghost which gets cut in half. .

I'm still a little confused about the part at 1:45 with the switches. Swear I tried that but I guess not.

@shlam None of these three approaches was the original design intention. This is the walk-through video: https://youtu.be/wJqzK5HrCSk

I genuinely can't tell if my solve was the intended solution or not because three moves in particular were very janky.

Were you supposed to stand on the lip of the raised area where the first connector is located while your clone then goes and opens the door? I feel like there should probably be a different move here but I didn't find it.
Were you supposed to hand off the connector to yourself from platform to platform? I quite dislike this move but I actually think it was probably intended.
Were you supposed to "scrape" the connector off your platform by activating the long barrier? Again I think this is probably intended, but it was quite janky. Took 3 tries to make it work and one of them the connector just plain disappeared, think it got flung from the world or something before rewinding it back.
