Notes:

Can probably save another 2-3 seconds with perfect gameplay and RNG as I had a few movement mistakes around the run.

I did get a perfect RNG on the run, there are a lot of places with RNG.

1. First Mudokon is RNG with how fast he will react (around 0.1 seconds).
2. First Mudokon in the first secret with where he will land on the portal screen
3. Bottom slig in the second secret, if he will say "wait" and wait almost 2 seconds before starting to walk.
4. Top slig in the third secret on where he will be possessed and what direction he will face.
5. Slog can kill you in the last secret, though it is rare.

Some movement "mistakes" I had:

1. 2nd secret, before chanting to open the portal, you don't need to roll, its faster to run and land one step to the left, but its much easier to fall by mistake so I decided on doing this safer strat.
2. You are supposed to run to walk in the screen transition on 3 minutes and 2 seconds (IGT) I did a mistake there and walked 2 steps, you can see how its done on my 100% IL run link below at 3 minutes and 3 seconds (IGT)
3. When exiting the portal after the 5th secret, there is no need to take a step to the right, I did it because it makes it easier for me to not hit the wall when falling down (which I still hit) you can see how not hitting the wall is supposed to look like on my 100% IL run link below at 3 minutes and 50 seconds (IGT)
