Mother Goose no Himitsu no Yakata (Japan) - PSP - Visual Novel

You, the heroine, falls into another world and has to find her way out via passing quizzes based on nursery rhymes. Apparently QuinRose hired a ton of different artists for the nursery rhyme pictures, and they''ll be featured in English with Japanese translations. It seems as though all the guys in the game know who the heroine is, but she doesn''t know who they are.
