Graphics is quite capable. For the Smartphone (Android) level, the graphics offered are pretty good.
Gameplay and Atmosphere are very different from most games. This is a First Person Shooter (FPS) game that is peppered with a ghastly scent of horror, and of course full of puzzles.
Rapid developer response. As a game that is still relatively new, all comments and complaints on Googleplay responded well. Active developers can create significant game developments.
Cons:
Nothing.
My Opinion:
The horror intense provided by this game (which I see from the demo video) looks quite stressful, but unfortunately this game is paid.
