The game, and the implementation, is fine. However, the best, BEST part of playing Scotland Yard is always the after-game, when you all burst out talking about how close you were back on move 20, where were you, oh my gosh I thought you had me, etc.
I'm surprised that zero thought was put into this critical part of the experience. You can't even look at the board after the game ends and they tell you Mr. X's final position. It just exits out and is lost forever.
Devs, if you are reading, I highly suggest you implement the ability to recap - you already have the turn counter at the bottom of the board. After a game ends, please let players tap on each turn marker and see where the pawns were at that point. It seems like that would be easy.
