I've decided to continue this project some days ago, and it's looking like this atm. I've been making lots of progress in it, and I may be releasing a demo/prototype soon, maybe in a month or two. I was really lucky someone suggested me an obscure "level maker" addon for Blender and it's really helping me a lot.

If you want to a great tool for making maps for your game, i suggest you Trechbroom, it's a map editor very interesting if you want to make PS1/N64-style maps
Also, it was originally aimed for Quake games, and your game is a retro fps in a mid 1990's style, so it should match with what you planned to do with this project

as far as I know this Trechbroom actually only exports .map files (I may be wrong)
what I'm using is "Level Buddy"
an addon for blender 2.79, it's inspired by quake level editors too
and it's working fine for me atm
but thanks for the suggestion!
I may take a look at it later too

the nice part about using f_g is the linking of entities and the map editor. For example, placing enemies, doors, linking interactive objects, triggers and so forth
I'm unfamiliar with level buddy, but that's the primary draw in reality of using that toolchain with TB/whatever .map editor you want
