|The Colossal Cave Adventure game, produced in the '70s, was the historic first "interactive fiction" game, in which the computer would simulate and describe a situation and the user would type in what to do next, in simple English. There are two versions both are console apps. Found on "http://www.rickadams.org/adventure/". Ported to Windows then to the Z. No Ipk file, unpack files where they can be run from console.
