Joey is a jerk.
It's a fun game. I think it has some game design problems, but it could be quite easy to fix by not allowing you to call bluff out of your turn. Otherwise game incentivizes passiveness and truth telling. Buying dices in the shop felt unnecessary. This game is good and has replayability without roguelike.
I think you should let them keep their personalities. I was quite disappointed Joey didn't call bluff every single turn on 2nd playthrough.
Graphics and sounds are phenomenal. Perfect voice acting.
