This turned out really great! I love the design and the limited vision mechanic. The art is very well done and gives the feel of being in the dark watery abyss.
When a survey mission to a remote corner of the South Pacific goes horribly awry, you find yourself trapped in a tiny submarine on the ocean floor. Your only hope of survival is to explore dark caves and mysterious ruins until you find a way to escape. With no weapons and no light, only your limited sonar and turbo jets can save you from the dangerous sea creatures that dwell in the deep and the otherworldly horrors that lurk in the shadows.
