I was able to achieve this time due to a glitch I found that allows me to jump SUPER high. This allowed me to skip all of the screens that turned upside down and what not.

You can Moon Jump by pressing two jump keys at the same time.

There were some moon jumps that I had missed in the second split, so this time is definitely improvable, but I think I'm done with this game for now unless someone else tries to contest me.
