Antumbra

Antumbra is a game played by Markiplier.

Game Information
It had been highly rated and proves to be very weird to say the least with its disturbing imagery and eerie atmosphere. It is also a very odd game and it's creepy, scary and incredibly hard. So hard that you should expect to die dozens of times. It is a point-and-click game with many hidden functions needed to advance through the game.
