Why obvious that its a seeded run? It's not it seeded, just took like all day to get this run using this strat. Also Guille has since then gotten a faster run since someone in china beat his time. This was world second and someone did what they said were 300 attempts to beat his. This is for a klei sponsored challenge hosted on bilibili, competing for a prize of skins if you get world record unseeded dragonfly speedrun.
here is his time which is now world record which he did to take back world record: https://youtu.be/zBA_axDO6yk
Here was the person he had to beat who still his method but did it worse (with a god tier seed): https://b23.tv/jyffUYT
Also why would I post this speedrun here when Guille already has seeded world record (albeit not by your rules since he didn't want to give the seed away and doesn't really care about speedrun.com much) https://www.youtube.com/watch?v=QOKPRRMUKAw
