you can play as an anthropomorphic dragon (more specifically the one from guncaster)
Have you ever wanted to play as the dragon from Guncaster without all those crazy (and actually fun) overpowered weapons? Well now you can! and it's all thanks to learning how to mod doom! (check the readme for how to install, even if you already know how to because why not?)
so how long until a demo of the mod
-Probably needs a class to select at game start, and some weapon sprites with hands for the original doom weapons.
-Marine voice sounds weird on Cygnis. A new class will allow specific sounds for specific "skins"
-Doesn't work in GZDoom, probably needs a proper re-write and use with an actual .pk3 rather than a .wad with the .pk3 extention.
IMPORTANT: I hope you asked the original author (Pillowblaster) for permission to use his graphics. I see him credited in the credits file included in the download, but it is missing references to the Guncaster credits.txt document which details re-use of materials. (also you didn't give him credits on THIS mod page, which is questionable).
