Neat! I was having a lot of trouble jumping on the platforms until I finally managed to see my character in double. Then I realized I needed to get the left one of them on the platform. I think maybe I was sometimes seeing (or focusing on) the left one and sometimes the right one earlier, which is why I was struggling? Is this something other people experience?
Kinda funny also how my eyes realized they needed to refocus right at the end to be able to hit the star.
