Unlocked the true ending?
Unlocked the first alternate ending
Unlocked the bad ending
Uncovered the identity of the dark figure
Put the four puzzle pieces together
Unlocked the sun and moon safes
Visited all locations shown on the map
Deciphered the message of the two sisters
Solved the card puzzle in the prison
Solved the sliding puzzle on the fourth floor
Caused Catherine's heart to stop beating
Unlocked the secret ending
Unlocked the good ending
Unlocked the second alternate ending
