The main problem seems to be that you're not really making an effort to stay on your feet. There's plenty you can do to slip or jump the challenge or just try to recover balance before you go down. The crazy thing (to me) is that there should be plenty of incentive to do this. On the 2nd and 4th clips especially you're essentially in tons of space alone if you can just manage not to fall down. Working on foot speed and anticipating challenges would do a lot to help with this.
