Deep sea adventures

In Deep Sea Adventure, you are a group of broke explorers sharing a single submarine and a shared oxygen tank. You dive into the ocean to collect treasures of varying values; the deeper you go, the better the loot. On your turn, you roll dice to move down the path. Every piece of treasure you carry slows you down and—more importantly—drains the shared oxygen every single round. If the oxygen hits zero before you make it back to the sub, you "drown," dropping all your treasures to the seafloor. It is a ruthless game of greed where you must decide when to turn back before your rivals use up all the air.
