A free app for Android, by Hector Santiago.

The application is a game, and it is rated for TeenFantasy Violence and Mild Blood.

It is basically a shooting game, where you will target a series of sprinting demons across some lot or misty clearing. You must shoot your target accurately or else they are going to escape into the forest beyond – and potentially add to their collection of victims. These crimson creatures will be very fast, so you must be very precise when positioning your shot.

There are many levels to the game, each one increasing in difficulty and acceleration.
