I don't feel like playing it in Japanese (the wordiness is about Ys level) as the only word I can decipher is の, but hey, a game of this genre by the makers of The Guardian Legend and Golvellius deserves some attention while Compile Heart shake their Agarest game at westerners. I hope it'll receive a fan translation treatment someday.
There's also a bonus puzzle game Wander Number on the disc, reusing Wander Wonder's graphics and characters, sporting the story mode and some multiplayer (?) options.
