Acedia: Indie Horror is a mystery game for your Windows Phone 7.x and 8 device that has a spooky, almost creepy, feel to it. Inspired by "Slender: The Eight Pages", Acedia is a scavenger hunt sort of a game where you are tasked with finding particular objects/relics to complete each challenge.
You navigate through what appears to be a vacant mansion where the only light is your flashlight to hunt down various relics. The 3D animations and graphics are nice and the soundtrack gives the game a suspenseful feel. As if at any second something is going to jump out of the shadows and eat your brains.
Movement and remembering your way around the maze of hallways and rooms are the biggest challenge with Acedia.
That and remaining calm. The game is played from a first person point of view with your movement controlled from the left side of the screen. You control your flashlight with the right side of the screen. What appears in the circle of light is well lit and everything else is dim. Combine the restricted field of view, the cryptic music, and the haunted house graphics and Acedia definitely taps into the horror movie mood.
Acedia: Indie Horror is creepy enough in a well lit room and for full effect, developer recommends playing Acedia in a dark room and use headphones. In just tinkering with Acedia for a short time, the only downside that jumps out at me is that you can't save your progress. If you make it half way through the challenge and exit, you'll have to restart from scratch.
Acedia: Indie Horror is a free, ad-free game for your Windows Phone that you can find here in the Windows Phone Store.
