It gets pretty fast as you go over 15K in a wish. And at that point, you really have to keep your eyes peeled for fairies to guide your landing. That's typically the time when I fail.

There's also one particular rock formation that's giving me grief. It's like a cliff you have to do a mini-jump up onto just before you reach the end of the platform and have to do the big jump. The cliff is always higher than I expect it to be and even if I do time the jump right, I bash into the star just beyond it.

I don't know if that's a good enough description of it. I'll take a shot of it next time it kills me if I can.
