Well, of course not everyone is a pro. But I said that because after I was rekt by Treylina, I decided to try another server. And I think it was called Puke Nukem Tests. That... amazed me even more!!! I mean wow! These were insanely hard levels and there were a lot of people going through them like they walk in the park. They maneuvered through tight and long obstacles without making mistakes. And I was like "Oh! So that's what the active JJ2 players are doing these days".
And I spend a few hours playing (more like struggling) through them, trying to figure them out. Eventually I learned some new moves and ways to deal with these insanely hard levels and made progress. So yeah. There you go. Not everyone, but mostly pros.
