After 10 tries, I still couldn't reliably get to the second platform. I realized that the camera angle was affecting my forward velocity, and tried to take advantage of that, but then I couldn't see where I was jumping. So I started losing patience. I made it as far as the 3rd platform a couple of times, but always slid off before I could grab the ladder/vines.
Sorry I couldn't see the rest of your content. From the comments, it sounds pretty cool.
