I hated having to do the whole Secret Base thing, where there's al the electric pads and when they turn red an alarm goes off... Yeah. I REALLY got ticked at that. But then, even HARDER, was Tiffany and her Camurupt. And then the Pupitar... -shivers-
I loved the three challenges! They're so fun, as far as I'm concerned.
... Then again, this IS my second playthrough of the game.
