Markiplier plays the indie game Mirror Layers for his viewers on YouTube. In the second video in this "Let's Play" series, Mark screams, gets confused, finds keys, and stumbles through gameplay as he is chased around a mirrored world. This mirrored world allows him to find additional pieces of information that help him complete puzzles he finds from the original house/world. Mirror Layers is a large community effort, and requires you to communicate with others via a Facebook group to get all the information that you need for each puzzle. It also modifies files within the game’s folder, making it a touch spookier than other games on the market.
