I didn't see any moving platform. The game starts with a vertical pillar that you can't ascend because the dash only moves horizontally, and I spun the camera all around, all I found was a platform behind me with a car on it. I was able to jump onto that no problem, but there's no where to go from there.
There is a sign at the base of the pillar that simply has an arrow pointing up. The goal is clear - ascend the pillar, using your movement mechanics I assume.
