Hm, looks like the models have the potential to look good but for some reason the image is grainy and faded or something, really looks PS2ish from that effect. If I hadn't tried it on two different TVs I would have blamed the TV. The animations are problematic independent of that though, especially for animals on the boat.
Nice effect that the plants get pushed out of the way of the camera, would be nice if they reacted to the diver's body too though (instead of just clipping through...). Oh and I first encountered the zone limits. Bah, those are annoying. You see something interesting and can't go there because the zone doesn't include it. I saw the blue whale but couldn't reach it because of the limit. Some other invisible walls are there too. I think those are a horrible idea in a game for casuals, they aren't used to the concept of simply limiting the playfield without visible obstacles.
