There's nothing overly complicated here. You just explore a maze, and must find the exit to win the 'game'. Sure, there's a few twists and turns along the way, as well as a creepy atmosphere, but I assure you as an explorer; this is just a maze. There's nothing sinister going on in the darkness. Nothing.
This is a screenshot taken from an early build, and is the first thing you'll see when you spawn into the game. There's a 'T' hallway, allowing you to walk in three separate directions, each splitting off to other paths and rooms. This is the final screenshot, and will be an accurate presentation of the game at launch.
