Nice idea and cozy game, the sounds are satisfying and you managed well to combine the limitation with the theme.
I've found it a bit too easy to gain money and I think it would've been better if you added letters to display big numbers like K for thousands, M for milions etc...
Also there's a small bug where the money goes negative:
other than that, for being the first game you made in 6 hours it's really good.
P.S. e sei anche italiano :)
