WOW! You beat me so fast after I replied :D What's even more impressive is that time starts when you jump for the first time (I did it that way because it was the easiest to implement at the time) and given that you start jumping from the center of the screen and you have to avoid some obstacles, you could probably shave off some time if you started jumping from the right side. That's what I did in my speedruns. Additionally if the camera behaved better and would give you more space for you to see ahead you wouldn't have to stop at 0:10 and you could just jump non stop. Maybe a sub 8 seconds is possible.
Congrats :D I think it's pretty safe to say you might be the best Bravest Chicken player in the world right now :D would you mind if I posted a link to your video on Twitter? I'd love to share your speedrun :)
