D.O.U.B.L.E.

This is a two player only cross between Pong and Breakout, which plays horizontally like pong, but you also have bricks to remove like in Breakout . It was coded by Matthias Weber and published by CP Verlag in the German based Disk magazine: Magic Disk 64 (September, 1989 issue). The game shipped with a level editor, though the instructions are in German.
