After you get the High Jump power-up, if you jump to the upper screen and then fall down, youend up in a harder version of the climbing section.
<sorry for the quality, I forgot about JPG artifacts and MS Paint>
Was it intended to work that way?
Also, I went pretty far into the laser climb at the leftmost part of the map, but I fear I'm missing the umbrella; wouldn't it be better to put an obstacle that requires the umbrella a bit earlier (same goes for the Hologram)?
