Treasures Of The Deep

You control a deep-sea submersible, guiding it down through dark water. Your main goal is to collect treasure and artifacts while avoiding hazards like mines and hostile creatures. You move the sub left and right with the mouse, and you can click to descend faster into the depths. The deeper you go, the more valuable the items become, but the dangers also increase. The pacing is steady, with a tension that builds as your oxygen slowly depletes. It feels like a quiet, focused race against time at the bottom of the sea.
