Uncaptive (Free Demo) - 3d puzzle horror sokoban [Mac, PC]

It's a story about a guy who got a message with an invite to check some strange place.

When he arrived at the right place he dropped down under ground, and realized that he is in a strange medieval room with a big door.  After the door opens, he comes to the elevator and hears a voice, that calls him to come down...

with 20 difficult levels (in the demo only 6), we will know more about voice and about the hero. Who knows maybe he never can rise to the surface?
