Ludochrono - Secret Identity

About Secret Identity, from BoardGameGeek:

ln Secret Identity, you must guess the hidden identity of your opponents while trying to make them guess yours. At the start of a round, you receive a key card that indicates your identity among the eight characters on the table. Using double-sided "picto" cards, you try to give clues to your character so that others can guess who you are, while simultaneously guessing their character - earning points for each success. Each round, new characters appear on the table, giving you and everyone else a fresh face to guess, but your supply of picto cards is never replenished, so you must be judicious when using them in order not to run out by game's end. After the fourth round, whoever has scored the most points wins. Will you be able to act both as a skilled informant and a sharp observer?
