It's yet another doom clone, but implemented in 13kb of (compressed) JavaScript.
Writeup of the development process: https://nicholas.carlini.com/writing/2019/javascript-doom-clone-13k.html.
If you just want to play the game (and don't want to play it online) then you can get started by cloning this repository:
git clone https://github.com/carlini/js13k2019-yet-another-doom-clone.git
and then just directly view the file doom.html from your browser.
From the main repository view the file src/webgl.html from your browser.
This file additionally displays the frame rate, some statistics on how many frames took longer than 16ms to render, and shows the map editor.
If you actually want to be able to build the small 13k version of the code and run it in this small version, there are a few more steps.
You'll want to run python3 make.py.
This will generate a few files, most importantly build/index.html which will run the game from there.
The additional files it outputs are also in build/, and consists of javascript files compressed with varying sophistication of techniques.
