Bruno R. Marcos has released Cavenaut, a freeware Windows action-adventure title starring an intrepid spelunker on a dangerous monochrome mission.

Gameplay resembles Konami's arcade classic Tutankham at first glance, though what starts as a simple snake-dodging action game soon evolves into something much more complex, as you can see in the trailer above. Players must carefully dig through unlit passageways and dodge numerous traps in an attempt to discover the meaning behind strange symbols that have appeared in the Peruvian mountains.
