Has anyone else had a problem with this challenge at all? I've sunk over 4 hours on this challenge alone in the last two days and just can't conquer it. I've done all these challenges before on ps2&ps3 (I love these games), and never found it this difficult. It seems a lot buggier on the vita than on the others (just keep getting knocked off the platform when I'm near the middle), and I've tried every technique and strategy that Google has to offer. Is anyone else having the same problem, or am I just getting useless in my old age?
