I really liked the first episode on Game Cube. The game was short but stopped just before being boring. This is écceuil where this falls on. Far too long and forcing the player to explore too many times the same areas because of its construction in chapter Luigi's Mansion will spoil what could be a very good play.
There is a very well made game with a very good atmosphere and friendly multiplayer, but its high repeatability spoil the pleasure that one takes.
