This game looks good and it's cool to see that you put some effort into the graphics to make it unique. Now it's missing something. Apart from the audio which would help with immersion and feedback, a feature to let us know how well we're doing (e.g. a score) would have given meaning to our actions. At the moment, whether I'm catching fish, destroying mines or blowing up the ship, it doesn't affect my game at all, and that can be quite frustrating. Anyway, it's still a fun game and you can be proud of what you've achieved in 48 hours! :D
