Black Swan has a nice presentation. The HOG scenes are not bad, although the objects are often too well hidden, or in the corner of the screen. The subtitles during several scenes don't correspond 100% to what is said. Some sentences are also strangely constructed, as if English had not been the source language of the project. There are few BGM and it's very repetitive. Apart from the scenes in HOG, there are some mini-games, but they are few and they are the same as in all the other HOG. (Assembling a picture, the pipe game, repeating the melody on a piano, etc.) I was hooked on the story at first, but it quickly became cliché and boring. Because "the spirit of a lady who made a contract with an evil entity for x reasons starts killing people and our heroine has to stop her by traveling between two worlds with a magic object", it's deja vu. Just see "Dark Arcana: The Carnival" or "Haunted Past: Realm of Ghosts", just for a character who travels between two worlds. So it's hard to recommend it, unless you find it in a bundle or at a very deep discounted price.
