I NEVER hear anyone talk about this game. I've never played it, nor seen it in action save for a few youtube videos.

The graphics look gorgeous, and the novelty of playing as a dolphin, along with the cool calm music and underwater setting, really make this seem like it would be more of a mood setting game, or an experience type of game like Rez, rather than an arcade or skill based game like shmups or fighters.

So, is it any good? Does anyone recommend it? Is it really short? Really long? I want to hear your impressions before I decide to buy.
