Really cool idea!
I like that there is both the element of taking the money AND the element of travel, adds dimentionality to the gameplay. There's more choices to make, so the game feels more complete.
But man, am I bad at math haha I was never sure how much money to ask for and maybe I'm too much of a goody-two-shoes because I never asked for outrageous amounts. Maybe I should have tried being a little eviller, would be better for me evidently!
Really great job, congrats!
