Atari's arcade original was famous for its trackball, so steering a marble down those isometric ramps with a joystick was always going to be a different kind of fight. Six courses of slopes, chutes, acid puddles and that green slinky thing that eats you, against a clock with no sympathy at all.
The C64 version kept the look and the cruelty. My marble found every edge there was to fall off, and the two-player race mode settled a few friendships. Short, hard, and impossible to put down after a near miss.
