Prolly this will help
Beat these levels in order
-back on track
-stereo ( harder than bot )
-polar
-dry out
-base after base
-jumper
-cant let go ( harder than jumper to newer players )
-fingerdash (EASY FREE INSANE)
-cycles
-time machine
-electroman adventures
-theory of everything
-clutterfunk
-hexagon force
-electrodynamix or clubstep ( both has the same difficullity, around insane and demon )
-deadlocked ( surprisingly easier than toe2 )
-toe2 (final insane ship and timings)
Dont trust the stars and the icon faces, sometimes an "insane level" are easier than a harder level, for example, fingerdash are stupidly easy
Trust me I have 65 demons
