The object of this game is to clear as many boards as possible by running your beamer over blocks. Movement is by joystick and your speed depends on whether a block is in the direction you are travelling. If there is no block you move slowly. If there is at least one block then you move along an energy beam at twice the normal speed.
The blocks are set out in different designs. There are two opponents. A yellow spinning ring moves about at random and there are chasers which follow you around. Hitting or being hit by either of these causes the loss of one of your three lives. The ring can change the blocks to energizers and, if you manage to hit one of these, your scores are doubled for a short while. Scores vary greatly depending on the distance travelled. Bonuses are awarded for each enervizer hit. The top five scores are displayed after each game ends.
The program loaded (eventually) though it took a long time. The screen display is good. I thoroughly enjoyed this game.
