A free app for Android, by Moustache Banana.

Welcome to Scary Head, the home for spooks, scary sounds, and all things terrifying. This game will test your courage as you battle through hordes of true horror, test the limits of your mind with puzzles, and question the realities around you. Get ready for a creepy adventure! You are trapped in a dark maze and need to escape. The only way is to solve the puzzles to get out of the maze with just your phone’s light guiding you. But sometimes, you’ll need to run faster than that light can illuminate because Scary Head will chase after you every chance it gets! The app is free and available now in the Play Store.
