For me who didn't play psp games
with art like that, at first i think it's child story (like doraemon or ninja hattori).
with thought like that make popolocrois is memorable for me.
Story: plot is rather flat, but the conversation, situation, and emotion is not the level for child story
Art: Surprisingly, with art like that it can show many mimics and emotion. and i become like this ^^
Sound: Amazing, opening is very great and ending is more popular than popolocrois itself (and have 2 versions, i love miyajima eri version)
Character: I like it. All character have plus minus personality
Enjoyment: not to good for me because flat plot. (there are times i'm bored in the middle of watching)
