Anarch

https://drummyfish.gitlab.io/anarch/

Anarch is extremely small, completely public domain, no-dependency, no-file, portable suckless anarcho-pacifist from-scratch 90s-style Doom clone that runs everywhere, made for the benefit of all living beings. It's greatly moddable and hackable.

I have now made quite a few mods to optionally improve the game, check out the repository. There is a consoomer edition which applies selected mods such as HD textures, particle effects, CRT screen shader, movement inertia, quicksaves at any point during play and more.

PLEASE: before  you decide to generously give me some money for this, download for free and try if it runs on your computer, I wouldn't want to take your money if the game for some reason wouldn't work. Thanks :)
