Dear developer, game is only 32bit. i can not crouch with ctrl button. i can not set graphics quality in game. I can not set vsync. Playstation 3 gamepad was not tested. Some images are little unsafe. I can not set music and sounds off. Volume control is missing. God bless you.
Sorry, I haven't had enough time to add proper menus yet, but they shouldn't be necessary. You can set the quality before starting the game, Vsync should be enabled by default. There's no need to crouch or mess with the volume, since both the sound effects and the music are part of the environment.
It is a game designed to play with keyboard and mouse (I think so)
