Even though this is an extremely old game (1984!) and even though it features archaic 4-color CGA graphics, it still can be fun to play. AlleyCat has you playing an ... uh, alleycat. The object is to jump around an alley (and also inside the appartment building) trying to collect as many mice and other objects as possible while avoiding baddies like dogs, sweeping brooms (?) etc. It's neat, and besides the fact that it's a true PC gaming classic, it's amazing how much gameplay is crammed into a 32k zipfile!
