This is the raw footage (no commentary) of my run from Completithon, which ended in a pb. Had a few costly deaths in 5-2 and A-B, was otherwise a very solid run with an absolutely insane 4th world.
This level has a repetitive cycle where most of the variation in what I do at the end of each lap is due to having to adjust to when I get the switches and whether I am jumping or on the floor to get them. Took 1 hour 45 minutes to learn the cycle to the first base completion, 2 hours 23 minutes to G++. Finished the challenge today - 3 hours/863 attempts for the whole thing. ???
