Okay...
It was an okay game. The graphics were good and I like these kind of games. However, I have a few criticisms. First, the controls sucked. The fish was unresponsive and hard to maneuver. Secondly, half the time that I was eaten, I couldn't tell that I had touched another fish. It seemed that all you had to be was close to another, bigger fish, which screwed me up because there were times that I could have squeezed past a fish, but contact was apparently not the deciding factor. So it was all right up until the point that I started dying needlessly in situations I should have and could have survived.
I didn't listen to the music, so I can't rate that.
