Nice world, and it's obvious what to achieve. Clear goal, that's always nice. But then the sharks... It seems that all sharks in the ocean are alerted and coming at me, even if I try to step in the water on a more quiet place. In real life I wouldn't dare to swim in that sea, and I don't know why the main character would do just that. A bit more of a story would be welcome and help me to persevere.
