i enjoyed this game a lot! my favorite character was grandma (the plot twist involving her was incredibly funny)
the game loop is actually really, really good, in my opinion. while it lacks a tiny bit of polish, something you're already aware of, it's still very enjoyable and, above all, original.
something you could consider adding, if you plan to keep working on the game, is a more noticeable indicator that you've received money. maybe a visual notification somewhere, coupled with a sound effect.
