That's valid, I think game jams are notoriously difficult to get completed games in (of course haha). tbh i can see why you'd assume no one would want to play the cookie clicker type game but honestly there's a really big fanbase for cookie clicker in and of itself and honestly I enjoy actively playing games like that so maybe I'm not the best guinea pig on the block :") Either way tho, I think a good way around this would be to make it more like a text box (like a phone notification?) that you can open up, interact with on like the computer screen, kind of like your coworkers are all messaging in a group chatroom or slack or something. That way, you kill multiple birds with one stone - You have a rereadable chat history, you can make the text more central to the game, and you can also have some sort of alert sound that tells the player when a message comes in. It would be interesting too to play with the idea of being stuck in a room - like you have a bunch of mundane tasks around the office space the player is in (among us style?) like reorganizing some files, dusting some bookshelves, etc. something small and boring so the player has every reason to sprint back to the monitor to read the new messages from their coworkers
Of course, all of this would take much longer than a week so the foundation you laid by having this game this complete in the first place is pretty good already. I can see your vision tbh and its pretty fire
