Cosmicube is one of those 'older games with a new twist' releases that you see every once in a while. The game uses the Unity engine to render a 3-D take on Marble Madness. The marble's track is made of red cubes mounted on a larger black cube. Your goal is to get a marble from its starting point onto the goal by moving your mouse to tilt the playing field. You're aided (and hampered) by an impressive physics simulation that feels very authentic and real, all while listening to a fast-paced soundtrack that fits the action and setting well.
