The new version is now available here on itch.

The new version adds a new type of unlockable photo, called Murals. Murals are larger images (400x400, instead of the usual 200x200 for the existing photos), that depict important events, such as boss fights, defeats, or game endings, and can contain any combination of the 5 characters in the game.

When unlocked, the character's present are saved. Murals can be viewed from the Gallery, like photos, but the player can choose to show or hide any of the characters who were unlocked during the event. In order to unlock all 5 characters, all 5 must be present, so the event will have to be completed again to obtain any missing characters.

There are 2 Murals in this version, one for each of the two Good Endings. Unfortunately if you've already completed one of the endings, you'll have to do so again to obtain the Mural as there was no way to have the game retroactively know which characters were present.
