Would have been faster if I'd practiced a bit, or if I'd played through the game at some point in the last few weeks (and therefore didn't forget some of the solutions midway through the chambers), but I figured I might as well record and time an attempt either way!

(Also mods, my apologies if I've got the wrong start/end points for the timer! :-) )
