Mars

Mars & Mars II are text based adventure games. These 2 are the same game, although the room descriptions are more terse in the original version. In this adventure you have to fix your spaceship to get away from Martians. The original ads for this program called it simply 'Mars'. The text descriptions Aardvark marketed this one as an easier, beginners adventure (although average playing time was still listed as 30-50 hours).
