Submarine

You control a small, yellow submarine. Your job is to navigate through a side-scrolling underwater world, collecting stars scattered across the seafloor and avoiding obstacles. You use the mouse to guide the sub, which moves with a gentle, drifting momentum. The main objective is to gather every star in a level to proceed, but you have to watch out for mines and other hazards that can end your run. The pacing is methodical, not frantic, requiring careful steering more than quick reflexes. It feels like a quiet, focused puzzle of navigation, where a single wrong turn means starting over.
