This is very impressive. That said, 1st person shooters seem like the less interesting type of game to create with an LLM nowadays. I'd much rather see a large world mystery game, for example. Think something like "All Her Fault", where you're the mom and you show up to pick up your kid and the game starts there -- and you need to find your kid. I would fine a game like that something that we probably couldn't do well w/o AI, but now, I think it might be doable.
