I think your video rendered incorrectly, it's a still image for the entire thing. I'm interested to see what it looks like though.
Whoops! Don't know how that happened. I reuploaded the fixed video here. You'll notice at the end the jumps stopped for some reason over the tracks, that wasn't me falling or anything it just stopped lol. Hope this helps!
Very interesting. I'm sure this will be fun to debug. Thanks for the report!
