Damn, I found it now, that it's totally Project DIVA clone, only with other music and models. That somehow makes this game interesting, but in other case makes to think (however, I do not think that someone doubted about that) that this is a formed platform and there is no problem to conveyorize it to whatever you want (SEGA want, exactly). But I'll try it very soon, I have no doubt that I'll like it :)))
