The post discusses a week-long project where a game inspired by DOOM and the backrooms, called The Backdooms, is compressed to fit within a QR code of 2.4kb. The development involved using minified HTML and a unique GZip method with Zlib headers to create a functional browser game from a small data footprint. It highlights the challenge of using infinite seed-based map generation under stringent size constraints required by QR codes. The author shares links to the hosted version, a repository for the game, and detailed blogs about the project's development process. User comments raise questions about QR code scanning compatibility, challenges with basic features like screenshots, and security concerns related to QR codes being a vector for malware.
