That's the kind of games where there is a lot to say, both good and bad.
What I liked about this game:
The unique art style
The musics
The premise that also translate into gameplay with the photos
What this game need (in decreasing order):
Polish! And a lot of polish. There are a lot of bugs in this short game.
-I'm pretty sure I saw all the photos except may be number 11, but I had only 8 unlocked at the end.
-Key items and the skill that gives SP targets all allies and can be used out of battle. Most skills can actually be used out of battle thanks to those SP.
-Burning flame don't restore SP but MP, by the way, MP are completly useless in this game.
-One case is impassable for no reason after activating the switch.
-The old librarian looks not to be the same character if interacted with from the side
-Some libraries seem to have a "under the hero" priority, making them impossible to interact with
-Probably some more I forgot
Better battles. Currently the game is super easy, any battle can be easily won by spamming the six hits skill. Some skills are also missing animations.
Replace the last placeholder graphics/SE
Give the F button an actual purpose, as currently all photos can be gained with the ok button.
Items and equips would benifit a lot from custom icons.
Give strawberry milk a price of 300 instead of 301. (Please...)
