I remember most of the rooms in metaspace from Dimension VVVVVV and the prequel
For example:
We Have Normality = The Sensible Room
Bus Crash = B-B-Busted
Stasis = The Final Challenge
Viridian Killed The Radio Star = Welcome Aboard
Under Pressure = Comms Relay
Aircraft Billy = Manic Mine
Entrance Only = Exit Only
Emergency Teleport = Exposition Room
D'oh, Really, Middle Of The Road, Far From Home, Solar Eclipse, LTIA Part V, and Tearfulness = the DTTHW challenge
Find Yourself = If I can't find a Warp Token...
Onwards and Downwards = House Of Mirrors
Checkpoint Processing = Even Shadows Need To Breathe
Sideways Pear = one of the rooms before the warp zone
This Room Had No Name = one of the rooms in the overworld
More Snakes = another overworld room in the main game
Joe's Building Salvage, Emotion Sensor, Incomplete Solution, and The Naughty Corner = Secret Lab
