I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha.

I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API.

This is of course a very oversimplified description of it, using a lot of the same technologies that DOOM had but combining it with infinite seed based map generation in 2.4kb (QR codes can only store 3kb, which includes changing formats) was pretty hard.

Here are some links about it if you want to nerd out and read more:

(PS: You'd need something like https://qrscanner.org/ or something that can scan bigger QR codes and put the text data onto your browser to play it)

Year 3567: automatic interstellar probe finds remnants a technical alien civilization.

Year 3678, Show HN: I compiled DOOM for an alien CPU architecture.

Vernor Vinge kind of touches this topic a bit in his Zones of Thought series.

How could one theoretically reverse-engineer a CPU?

With an electron microscope possibly.

Sometimes, sometimes just optical, but in any case, there's even a guy, Ken Sherriff, who has been doing this as a hobby for ages. It's not like this is merely theoretical.

That's cool. Thanks!
