A free app for Android, by David Zobrist.

A race of unusual, undead living forms was discovered by our scientists. We had no idea that our tests would frighten the animals and nearly render them unmanageable. We dubbed it “Creepy” since we were compelled to tweak one of them so he could fight his brothers.

We tend to be more immersed in virtual reality when playing horror games, so whatever we experience during the game—be it anything—we feel through every hurdle we encounter or every time something unexpectedly crosses our path. Our body tends to create a variety of chemicals in our brain once this occurs, or if we are scared or frightened, and these hormones also include dopamine, glutamate, and serotonin.

So get this app now and experience a mix of horror and happiness in one!
