Not the WORST thing in the world, but very forgettable, especially compared to the console versions. The 'boss fights' were simply doing things on the touch screen at the right time, like frantically turning a crank, and hoping for the best.

The actual clue-gathering portion beforehand, aka the very basic puzzle-platforming with the disguises, isn't memorable in the slightest. I can't even remember what disguises were actually in the game!
