Thanks for playing and for the feedback! We didn't think of adding a sensitivity slider because of the way the submarine is handled(an heavy object with weight and drag, rotating with motor), but it might not be a bad idea to add one. As for the monsters, it's them that mimic the shape of the submarines. It's like a shapeshifting creature that take the global shape of their prey. I didn't think much of the "lore" to be honest ^^
