Thanks for your interest and your comment !
You don't require knowledge of the full game to understand, play and (may) enjoy our video game. But it should be necessary to understand the whole experience we tried to create through the combination of multiple types of game. I correct it in the description, passwords were used during the boardgame phase, players could obtain some, usable in our game, giving them bonus/penalty, but you can play the game without enter a password.
