Doom in Brainfuck

Doom in Brainfuck is a project that compiles the entire 1993 DOOM game to Brainfuck, an esoteric programming language with only 8 instructions. It runs as a playable game by replacing OS calls with custom input/output handling through UNIX pipes, demonstrating that complex software can be implemented in Brainfuck. The project includes a Brainfuck executable and a frontend to play the game.
