​As you progressed through the cave tunnels, they slowly tightened until you could not even stand. Now, as you crawl, you wonder if you are not alone in the darkness.

Those Who Crawl is a tense horror game about crawling and climbing through cave tunnels. Each hand is controlled individually with a unique crawling and climbing system.

The walls are closing in.

As you progress, the stone walls become flesh and bone. The water in flooded tunnels is now blood red. This would be a horrible place to die. Now in the darkness, you hear something moving ... something with many legs.

Cut the flesh.

Utilize sharpened bone knives to cut away at the sinue and flesh that blocks your path. Stab them into the walls to make improvised handholds. Be careful, however, as the fragile bone will break after several uses, leaving you without a lifeline.

Things are moving in the dark.

Creatures lurk deep within the tunnels. They are bigger than you and faster. You can't fight back. Your best bet is to run - or rather desperately crawl. You could try using your knives, but would that even work against these monsters?
