Micro Submarine

You control the submarine directly with your mouse, guiding it through a narrow vertical shaft. The immediate goal is to avoid colliding with the creatures that swim up from the bottom and the floating bombs that descend from the top. The mechanics are purely about evasion; you constantly adjust your position, sliding left and right to find gaps in the traffic. The pace picks up steadily, and the shaft feels increasingly crowded, making even small movements critical. It feels like a tense, focused exercise in threading a needle while the walls are closing in.
