This game is pretty unique. Different but fun.
The controls are a little different at first. And this is the only really complaint I have about the game. You control yourself by pointing the wii remote and holding the trigger. You basically point in the direction you want to go and then press it to swim. Pretty easy, I know. There is even an autoswim function so you don't have to hold down the trigger.
So what is my issue? Well, this game is a relaxing game to me. I usually play it before bed, after I've had my Mario Kart multiplayer fix and after bashing some heads in No More Heroes. This is one of those games where I want to lay down. I don't want this game to be a physical game. Now, pointing the wii remote doesn't sound like much. But you're constantly having to move your wrist or hand to navigate. It just gets really old after awhile.
What I wanted this game to have was an ability to plug in the nun chuck and control yourself with the thumb stick. This option would have made this game a hundred times better. Then I can lay down and not have to constantly point the remote at the tv. My hands, arms, and wrists can just relax in any way they want.
Other than that, this game is great. The sound is very relaxing, the graphics are great. The sea animals are awesome. And with such a low cost, you would be crazy not to have this game in your collection.
