A game set in 4D euclidian space. Use WASD keys to move around, and use the mouse to rotate the camera. Hold shift to change your keyboard and mouse controls to 4-dimensional movement and rotation. While Shift is held, the W and S keys move alond the W axis relative to the camera, and the mouse rotates on xw and yw planes. A and D keys are unaffected by holding Shift. Rotate the scroll wheel to rotate the camera along the zw plane.
