Throughout these last years, many developers have dedicated themselves to executing doom on increasingly complex devices, such as in a PDF, in a pregnancy test, in Microsoft Word and even in a block of lego, but it is also possible to execute it in a QR code.
The developer Kuber Mehta has published a project called Backdooms in which, basically, although it does not execute the original doom engine within a QR code, Yes, it has been inspired by the classic shooter and the Creepypasta Viral Backrooms to develop this project.
With this, he has published Backdooms which is encoded entirely in a single QR code, which when scanning an HTML environment of infinite generation that resembles Doom’s halls.
Best of all, is that the game is so small, that it can be executed in any browser, since it is stored in the URL itself, and does not even require Internet connection.
As explained on the project website, I wanted to execute code within a 3KB QR code. For this he had to resort to a technique called Minification To compress an HTML program in a small space.
Thanks to this compressed code, graphics can be generated and, in general, those doom -style halls.
He also used the web API called DecompressionStreamavailable in all modern browsers, to make the code of your project dynamically decompress when running directly into the browser.
Although obviously the game does not really look like Doom, it does keep that tradition of the halls alive and that milestone of executing the program in places of little memory.
