Fahrfall is a homebrew game for the Color Computer 1 and 2, created by John W. Linville between 2012 and 2015. The object of the game is to guide a character on platforms and fall to the next ones, trying to avoid the fire coming from above and the abyss below. Your score is your calculated time you can stay alive.
