This is already the fourth game in the series which obviously means that you guys really like this kind of hentai games which allows both to enjoy beautiful artworks yet at the same time will make your mind. Each time you will flip teh page of this virtual book you will see two seemingly identical pictures but each of thes epair swill have three difference spots which before going to the next page you will have to find. The deifference spots might be both quite obvious (like the object missing one of two pictures) or they can be hidden really well (for example it may be the difference in the size of objects, altered color scheme or something like that). Will you be able to find them all? No need to guess when you can try this game right here and now!
