if nobody has completed a full 21 double jump run maybe someone could splice clips together to form the fastest possible 21 double jump run at the moment

only issue with that is nobody has ever beaten level 18 with its minimum amount of double jumps, because it has a trick in it that consists of 5 frame perfect inputs and a perfect setup. Along with that, only 1 person has ever done the trick, and it took him over an hour and a half in order to do it. Not to mention there are other levels that are REALLY hard to do with its minimum (level 15 comes to mind) and although the trick has been done, the full level has never been done

tldr: level 18 hard and level 15 hard

level 18 is so easy I can do it on the 1st try!!

yeah level 18 is easy as shit, but beating level 18 with only 2 double jumps?? yeah not very fun
