After spending some time on this level, it's actually not that difficult really. The passovers and the final activation of the Tadpole all have straightforward timings. It's just takes time to get them all in a single run.

It took 1h 46min to get my 2nd completed run in this session (first being a bad 1:22.95). And thankfully it was without the Tadpole landing on the edge, resulting in a insanely good time! I'm unsure if I will continue improving my time to inch closer to the "Normal" world record, or if I will pursue the "Checkpoint" world record, but we'll see in the future how I feel.
