I got nerd-sniped into the GitHub Copilot CLI Challenge and made a questionable decision: I turned my codebase into a roguelike dungeon.
It started with a simple prompt: Build a GitHub CLI extension in Go that takes the current repository and turns it into a playable roguelike dungeon, with dungeons generated with BSP [snip]. And then /yolo .
The result is GitHub Dungeons, a terminal game that generates a dungeon from your codebase. Rooms, corridors, and enemies, all built from your repo and rendered right in your terminal. You navigate with arrow keys, fight bugs, and hunt for the exit. Every repository produces a different map. Every commit reshapes the layout. And if your HP hits zero, you start over.
Roguelikes trace back to games like Rogue in the 1980s – terminal-based adventures where each run generated a new dungeon, and death meant starting over.
That combination of procedural generation, permadeath, and text-based interfaces (later formalized in things like the “Berlin Interpretation”) makes the genre feel surprisingly modern, and a perfect fit for the command line.
