The Treasure Ocean

You control a diver, moving them left and right across the seafloor with the arrow keys. Your goal is to collect enough treasure items, like coins and gems, to complete each stage. The space bar lets you pick up these items or sometimes interact with chests. The levels are short, presenting a clear count of how much treasure you need at the top of the screen. The pacing is steady, and while not overly difficult, it requires some careful navigation to gather everything. It feels like a calm, methodical search, a quiet task of clearing the ocean floor piece by piece.
