In this game you must roll barrels through a maze and into one of nine boxes at the bottom of the screen.
The vertical walls of the maze are gates that change their inclination as the barrels pass through.
The order and manner in which the barrels must enter the boxes becomes more difficult at each of eight levels. Although this change in objective adds variety, it is more suited to younger players as it becomes rather repetitive.
Penalties are invoked whenever a barrel enters a box already occupied. When the supply of barrels is depleted, the game ends.
The excellent eye catching title page is a forerunner of the splendid graphics, confirmed in the demonstration sequence.
Chasing a high score is well catered for, with the scores spiralling upwards in the higher levels. Full instructions are presented on screen and are duplicated on the cassette inlay.
This seemed best suited to the keyboard. Joystick control is available. Pressing 'E' causes all gates to be reset randomly, a useful ploy when the going gets tough, as it does in the higher levels.
Another aid is the ability to scroll the centre of the maze to change the playing area.
Nice to see an original idea that works well as a result of its simplicity.
