Another example of video game logic in anime. If you want a coherent story, then no, no thanks. If you want something with deeper meaning then no. After watching you feel like you gained nothing, since it's ultimately a worthless experience. You can really tell that this is a visual novel. Main character doesn't have a name. You get a boyfriend after a boyfriend, each time they have a different story but you don't get much into it, there are always some problems, some tragedy, some drama, you don't know what's going on, you don't know what's real, you don't know why this strange creature caused your amnesia and hopping between alternate universes for the convenient harem purposes.
It's not entirely bad, I guess. It's pretty, some events are interesting... but still, it doesn't make sense. Also, it has no ending. Obviously, since it's a harem visual novel.
