You definitely can get a 0/10 run and i think there are a bunch of ways to do it. If you want to climb the last white wall, you can press jump while the game is paused and it gives you an extra jump.
Thank you so much! I'm definitely going to continue working on this, and sound is definitely on my to do list. By the way, if you run out of time and then press r, you'll unlock another power up.
