This is Fluttershy as a Doom 2 map (with standard textures only), made by hand using SLADE. Some shapes aren’t perfect, but I kept running into unrecoverable mapping errors when making the finishing touches so I let it be.
It can probably be made to look better/more recognizable by making a custom texture set too, maybe I’ll look into it for fun.
Here’s the WAD (only works with GZDoom), if anyone wants to try: fluttershy.wad
