I got stuck in the casino in a loop of losing all my money after a while I wasn't sure if this was a game or my life...
I think if you used some voice actors could add a lot to the experience ;) (maybe elevenlabs AI if you couldn't find people).
Your dad says that you should gamble on all machines before giving up (at least the different types of machines)
And about the AI, I was gonna add effects and sounds but I had to go on vacation the last jam day.
