The Dark Castle is a horror -exploration game where the goal is to collect three gems. WASD to move, left and right arrows to turn, W+up arrow to run, and Q to check the locations of you and the gems. The location of the gems is shown in the coordinates in the parenthesis. Each gem is at a different coordinate. Once you go to those coordinates, look around the room for the boss entrance. Enter it, escape with the gem, and once you have all of the gems, go to the exit, which will now be shown in the locations.
