I get sad when I see others get angry at Uumuu. Sad, because I know that they’re actually angry at themselves, for having terrible Watcher Knight and Hollow Knight fights. Because Uumuu is so easy to optimize, they take their anger out on him, becoming more and more insecure and never addressing their own personal problems. I just wish more people understood that RNG doesn’t ruin runs: speedrunners ruin runs.

Minisavestates is indeed allowed. You can see this and other rules for it by clicking the View Rules button on the PoP leaderboard page, just to the left of the "Submit run" button. :)
