Not my cup of tea (particularly not a fan of the changes to the weapons) but I appreciate the work you put into this.
In case you're interested:
Tested it briefly on some id1 maps (using Quakespasm 0.92.0 on Linux), and encountered missing textures on the following models:
The hurt/dead Ogre
The hurt/dead Rotfish
The gibbed heads of the Enforcer, Death Knight, Rottweiler, Fiend, Vore and Shambler -- basically all monsters except Zombies and Grunts (and Rotfish and Spawns, obviously, since they have no head models).
Examples of what I mean:
Fiend and Death Knight heads
Dead Ogre
When I activate noclipping, my forward key (mapped to "w") is stuck until I press jump (spacebar); then I can move around normally. Not an issue during normal play, but odd and somewhat annoying nonetheless.
Also, any reason why you included a config.cgf in the download? It messed up my video settings. Most of my other settings were the same as in the config file anyway -- but they could have been different, which would have made it even more annoying. I mean, it's not hard for me just to delete it, but it seems like a good way to scare off potential players of your mod (e.g. people who don't know what a config file is or does, and will just see their settings changed and decide not to bother anymore with the mod).
