Anyone know about this game? It's appeared on both Japanese and European release lists (as "Petit Virus") and I'm somewhat intrigued. Even though I don't have a damn clue what it is. The publisher is "Keys Factory", seems to be mainly an accessories manufacturer.

age for general curiosity

Says it's a puzzle game. So, yeah, it'll be another Dr Mario/Puyo Puyo-style object dropping, or a Panel de Pon/Bejeweled style flipping tiles around. Probably with some "inventive" use of the stylus.
