Deep-sea adventure

Deep Sea Adventure is a game where you dive deeper and deeper by rolling dice. The goal of the game is to collect more treasures than all other players and bring them back to the surface. Several adventurers are in a submarine together and want to bring the treasures slumbering on the seabed to light. They all put on diving suits, but because the submarine has seen better days, there is only one oxygen tank that everyone shares. If just one of them dives too deep, everyone else is put in mortal danger! Will all the adventurers manage to make it back to the surface with their treasures?
