This with some multiplayer would be so fun to bring around! I've been having a ton of fun playing this and actually enjoy the more quiet tone of things, it'd be cute to have some minor ambience to zones instead of music though!
I also like the idea that like, people actually do stick to the rules of the game despite it not being a pokemon type deal where they are sorta at the mercy of explosive dogs or flaming birds if they lose, like there's no actual risk if a city punk didn't hold up his end of the deal on a loss but he's like "Well it wouldn't be cool of me so I better stick to the honor system" lol
