I like the sound when the coins pop out, it sounds like making popcorn! I think it would be cool if his property also showed an increase in wealth. maybe he builds a golden statue of himself and it falls on him. I had fun, good work!
I like this idea a lot, i think it has potential to be a very dynamic game if you were to implement a sort of "the upside down" to the inverted side. Good and Evil, Light and Dark, etc. This is fun to play!
