Very challenging gameplay! I really like the shattered glass effect of the submarine :)

Nice idea for the game, fits the theme perfectly. I didn't like the graphics tho. The font is hard to read, at least to me. And the lighting is a bit hard, not sure if it is intentional. The concept of what you're supposed to do is good. I find the controls to be a bit difficult, maybe because I'm not used to games like this.
Good game, good job
