This was basically a really fun (and cute) side-scroller/RPG (trust me it works).
A very fun and unique game, but also very Anime in look and feel...I can only guess that at the time of its original release on the SFC, it was felt that it wouldn't appeal to American audiences. That's a shame because it's a fun game and deserves to be played by a larger audience.
It would be a shame if this Super Famicom gem went untranslated forever....
I must reiterate however that this is NOT a request for translation, it is a request for information as to whether or not such a translation exists or is in the works... I only remark that if there is no such translation, it would be a shame.
