Really great art style! I love the use of a 'physical UI'. The way you get your payout is also really fun and satisfying. Definitely a good prototype you can build further on.
There does appear to be a problem with the coin bag, at least for me. In the screen shots i can see there should be a coin counter on the bags. But i could only see some unreadable white text. Luckily it's possible to just physically count my coins by taking them out the bag, which is a fun workaround.
