Your three-year-old grandson has gone missing and was last seen headed in the direction of the abandoned family farm.
It's a dangerous place to play. You have to find him before he gets hurt, and it will be getting dark soon...
The game was originally written in C for the Replica 1, an authorised clone of the Apple 1 computer.
Because it was written in C, the game is easily portable to other platforms.
The author himself has produced versions for Android, Raspberry Pi, Linux, the Altair 8800 computer running CP/M, and Arduino.
Another version of the game was produced for Arduino (by Felix) that was playable using Morse code; see here.
benkid77 has produced a YouTube walkthrough of the Altair 8800 version of the game.
