The movement mechanic looks original. The hunting process doesn't seem clear, maybe it would be great to see more effects. And I'd like to getting something rewards: score or bucks. But this is minor flaws, overall it looks good. Usually I see fishing games, but it's underwater exploration, hunting without killing. I really like this idea.
Possibly I have too little experience in playing games (typically I play here, and avoid Steam). But I'd like to play full-featured variant of this game one day. I think this concept has potential.
