Is this game good? What kind of game is this?
AngryLittleChemist's post answers the first question perfectly, I think. As for what kind of game: think of it as Twilight Princess, but with better art, more talky parts, and simpler puzzles that get spoiled for you by the game itself about five seconds after you encounter them.
It's genuinely not a bad game at all, mind you, but it's far from a great one, and it overstays its welcome about halfway through.
