Well, you get what the title promises, you become a shark. I like the light summer vibe this game gives, although at the start you have to kill 50 people (it's clear the protagonist is more like the psycho shark of Jaws, not just a dude out for a lunch). Of course, once you discover the other even more unrealistic aspects, it all changes. Not sure about the handling of some features, the map in M button is sure logical, but it's not the easiest to reach (maybe combine it with the pause menu), also the camera in some places (like near the water surface) is a bit dodgy at times.
I'd like to invite this game to our contest, the Game Development World Championship!
