Behold! A single QR code containing a miniaturized take on Doom: 'literally the entire game'

A QR code encoding Kuber Mehta's the backdooms game has seemingly emerged from a Doom 2016 demon portal. The Doom Slayer and a nearby demon look on, bemused.

There's something a bit magical about shareware stalwart Doom and folks' compulsion to make it run on absolutely everything. Present a sufficiently motivated individual with the game's open source code, and a less than powerful bit of kit offering maybe the barest whisper of a GUI, and you can be sure they'll put two and two together.

So, when I ask 'what does a pregnancy test, gut bacteria, and 100 pounds of moldy potatoes all have in common?', you know the answer. Well, now we can add QR codes to that list—with an asterisk. Developer Kuber Mehta has created something exceedingly light-weight that can be compressed, encoded into, and then extracted from a single QR code (via TechSpot).
