Obviously, the tutorial appeal of RobTop levels wears off over time, but there's certainly something to be said about how effectively Rob's 1.0 levels communicate their progression tonally - Stereo Madness's loud red breakdown being followed up with the game's most spacious ending sequence will be iconic for all time, and 1.0 visuals do have a certain classic sharpness to them that almost feels retrofuturist. Maybe that's just nostalgia talking.
