I actually did this ~6 months ago as my first ever difficult exportless map and have since rebeaten it multiple times in both BE and v7 with different strats, this is just the first time I managed to record the whole run.
A few sketchy parts with my reign nearly dying at the end (wouldn't have mattered anyways) which could've been otherwise avoided by not being so reckless.
Not too difficult with practice, highely recommend you go for an exportless run if you wish to be able to do harder maps.
I did tack on the added challenge of no logic and no schematics (although attentive viewers may have realised I recreated qwerty's 7 plast schematic by memory which was funny)
