What did you think of the Temporal Rift challenges in FFXIII-2?

I didn't mind the ones where you had to connect the same coloured crystals, or the one where you had to find the right path over the tiles.

But what I DESPISED...

THE HANDS OF TIME.

The first couple were easy but they became ridiculously frustrating, didn't like them at all. I tried to work them out myself but in the end I looked online xD
