Multiplex
Multiplex is an ASCII action game for DOS, in which your mission is to make as big as possible explosions, while avoiding that you explode yourself. You must kill all enemies in every level, either by crushing or by running into them. If you die, you may continue two times from the level in which you died. The third time, you must start over at level 1.
I read from the zip file that this game is created in quick basic and the source is available on request. But the email id mentioned is invalid now. Any way the source for this can be obtained? I am interested in learning quickbasic 4.5
