First Thoughts:
Interesting, although you do have a long way to go, it seems you got the framework made for enemies and their behaviors, which I see as a good foundation, the only issue here I see is just polishing and making it look good. If you're focusing on foundation I'd say these block window tests would do fine if you can't polish the game with models, props and such,
Questions:
What kind of content you're planning to include in this game? Anime, furry, or something else? Got a target audience? Or can't answer?
If this is going to be inspired by classic doom, do you have 3d models in mind to use or is it going to be pixelated like the real old school DOOM games or Wolfenstein, or you can't answer? I'm fine with any personally.
Issues so far:
I so far have no issues with the game or bugs, but I did laser the boss down during their supposed "intro" with a rpg spam paired with a SMG so I actively held back to prevent neutralizing them in one volley.
Unless the enemies are going to get so overwhelming later on the RPGs rate of fire needs to stay the same.
Feedback:
Lewd TV, sounds like this game takes place in a cyberpunk like era, will there be neon in this? Or will this be in some other time?
I do like in game there was a showcase of how sex scenes will be done even allowing you to see it in any direction. I can imagine its gonna be difficult for you to do.
