Real talk - The closest thing to a glitch in this game is the checkpoint manipulation on Crawler-Monster, Runner-Highroad, and Runner-Fire Escape.  Other than that it's learn the track color signals, and Do The Twist (TM).

That said, I'm leaving this playlist of ILs here.  I highly recommend watching the newest best full run or just skipping to the appropriate track though.
