This game tries to go deep in the mind of a serial rapist, going all the way back to the Vietnam War. You can play during the war, too, and find out what exactly happened there. Because of the theme, the gaming experience is naturally pretty heavy and might be offensive to some people, so it's not recommended for everyone.
Besides the theme, Edmund has a simple 2D gameplay. You can jump (which is necessary) and shoot a gun (which is only occasionally necessary).
Edmund is a strange adventure. Beneath the gloomy graphics, there's a strong adult story that is rarely explored in the world of video games. It's a unique experience for sure.
