Gyroscope
Releasing a game that resembles a well-known arcade game before an official license can be released was always a challenge for publishers, and in this case Melbourne House released a game similar to Marble Madness. Controlling a Gyroscope, the player moves along a sloping track full of hazards. The viewpoint is in fixed isometric 3D, with hazards including buildings, ramps and drops. The Gyroscope accelerates quickly and is slow to brake, so it is easy to enter a screen too quickly.
Not keeping the Gyroscope spinning freely while navigating them costs you one of your seven lives. You also play with a time limit: if you lose a life you go back to the beginning of the level without recovering the lost time, but if you run out of time you lose a life, but you can continue from where you left off with a new time (so, like in Chase HQ, completing complicated levels can take 2 or 3 lives at first).
You get time bonuses for completing a screen, point bonuses for completing one of the seven four-screen levels, and an extra life for reaching 1000 points. At the end of level 7, you will get 1000 points for each remaining life, doubling your current amount of lives. You will then start again at level 1 but mirrored by the vertical axis (you are now climbing from the bottom of the screen to the top). After level 14 (mirroring level 7), you will again gain 1000 points for each remaining life and then the game loops back to level 1 (not mirrored).
