I have it noted (almost first, in fact) on my list to play it, I saw when it came out and it has that aura of mystery/terror that intrigues me quite a bit, I can just imagine the sea creatures that might come out, it looks really cool.

Our hero can control the fishes say, piranhas to cut the ropes and let him advance to new levels.

This surprised me, I thought he was a simple sea diver, but I see he is not, makes it even more interesting!
