This is a very unique game, but its controls can be confusing at first.
Audio- There's only one song pretty much. It's Luigi humming. What is cool is that it changes depending on the situation. When there are no ghosts, Luigi is calm, but when low on health, Luigi starts trembling in his voice. The ghost shrieks also may frighten you. The music sets the tone of this game well.
Graphics- The graohics are good, exept that the environments are closed in. This fits, I guess, since you are in a mansio filled with rooms. The physics in this game is superb. Almost everything reacts to the vaccum, so you'll be sucking through everything in a room before leaving.
Value-The game only takes about 5 hours to finish, and you can play through it again with a harder difficulty or to get a better rating. This makes this game more of a rental.
Tilt (Innovation)- The control scheme is nothing I've ever seen before, and it works well. I've also never seen a ghost catching game this addictive. I hope more games will be creative like this.
