You've put down a lot of ground work here and I think some focus would help. Maybe try to narrow down the idea to a few key elements rather than trying to have the game do too much. What do you think the player fantasy is with this game? What do you see the action looking like? I was having trouble visualizing this as a card game which you mention being a possibility. Overall a lot of cool ideas here about the sheer ridiculousness, madness and darkness that comes from working in an office environment.

I admit I found it a bit hard to create a coherent and straight story, mainly because the story doesn't really have one, it's just the premise; that's why I tought a card game, as gameplay, would fit. This way I think I don't really need a deep story but just well thought symbolism and a solid worldbuilding. I took Inscryption as an example, it doesn't have a really deep story but it is mainly about lore and worldbuilding, but this is masked by a good gameplay that keeps you engaged which is the card game.
But after all this I admit that I just got inspired about this idea and it was my first time playing around with this kind of idea about unseriousness and absurdity, so my inexperience got the best of me, but feedbacks always help to improve
