Wu's been posting super low quality videos of her "speedruns" trying to get on to the leaderboard. Example:
https://youtube.com/watch?v=uZ2fU6UdfAQ
It's a terrible, completely unoptimised run that any real speedrunner would be ashamed of. She even dies at one point.
Here's Wu's speedruns account. She's submitted a run and checks every day to see if it's been verified, but nobody has given her the time of day so far because there's no info about how she was playing, no timer, no splits or anything you'd expect in a real speedrun video.
The thing is that the category Wu is competing in, All Stars Princess Only, is a bullshit category nobody runs. There's only 33 runs total registered over the last 3 years. Nobody cares about it because it's not a run worth doing. Wu only runs it because it's princess and she's a totally real girl, you guys.
