The game featured pictures of Maria with upskirts and that kind of stuff, but nothing that was too far, and you played as Maria, with the turtle rebounding and clearing Castlevania enemies on top of stage, alla Arkanoid.
It was really fun and challenging, but it's been years and I don't remember in which DVD backup I have it, and I don't have it in my computer, neither can I find a link for download (even in 2.005 it was hard to find the full game, but I looked for it since screenshots were everywhere). IIRC, they were 5 games with anime girls, most of them with CV girls, and some mods of fan games including Maria Renard (like Ieyasu, CV3 remake and SVK4, but with a playable Maria Renard in all of them, in addition to the other 4 or 5 games where Xtacy was included). In total, they were like 10 games with Maria, in a pack. I can't find it now.
