Sunken is a game about building and managing a deep sea research laboratory. It draws influence from Dwarf Fortress, X-COM, Spacebase DF-9, and other sim/management-focused games. In Sunken, the primary enemy is the environment itself, miles below the surface of the sea, where any slight failure could cause the death of the whole colony.
Water pressure will cause overly large/open rooms to eventually cave in. Structural stress is shown in the image as orange - this will eventually be replaced with a "cracking" animation. Click "view original" to see animation.
