excellent, chouette énigme à résoudre entre amis
Super enquête pour découvrir Bruxelles
Chouette d'expérience, super drôle !
on the long side
Harold le petit coquin
super jeu sauf qu il ne faudrait qu un seul téléphone par groupe car quand une personne valide,
plan un peu trop imprécis. \nun système tels que Google maps serait plus adapté et plus réel
les transitions pourraient être plus réfléchies et élaborées \nune histoire moins obvious
Un peu longuet mais très bien construit ! Fait découvrir Bxl
Petit bug à la banque. À part ça, super aventure !
