Good job. I tried to make another speedrun so I can get 1st place but I only did 15:35. I analyzed and compared my speedrun to yours and I figured you're more skilled then me.
Tip : I did this im my second speedrun that I didn't post. At start, you can accualy go behind, jump and dash, and get to a little "pipe", or whatever it is, from there go up and at the top jumap on a box and then on another pipe. Like this you get past the 3 red balls in 1 minute (a bit less then in your speedrun). This is all pretty hard to do, especially the jump and dash from the start.
Hope I helped you ;)
I posted the run once but it didn't get verified for a whole month so i posted it again.
I beat ur time. I did 15:58.
NERF THE DASH… I used the dash to skip like half of the pipe/tube level
