110+ attempts on something that looks easy but felt SO MISERABLE because of
1) Picking up powerups by mistake
2) either the Cacos flying around the skybox,
3) the Cyber not behaving or rocketing you off the platform
4) An 80 damage missile throwing you also off the platform (funnily enough I took 3 in a row in this one)

This is the safest approach I think someone more skilled can definitely do better.
