Is it possible to get speedrun.com categories for this? I have no idea how any of that stuff works, what the process would be, but I notice "Getting Over It - Category Extensions" has a section for speed runs of player made maps, and personally I find playing this version really refreshing (if significantly more challenging).

I had to go for it :)

Haha this is insane. I've only managed level one so far because I'm using a trackpad on my work laptop, I'll have to check this out properly when I get home.
