Hi there.
1. I give this one 4 stars, 4 for the (imo) very good writing and depiction of the characters, -1 for the ending with "the voices" which was far too "typical human thinking while being in divine spheres". You should give it a try, if you're not afraid of a few tears (perhaps) and some deep thinking about your own life, then you should definitely go for it.
2. There is no se. content to look upon, there is one love scene, however, which is fitting (perfectly) into this novel. As usual I don't care about the missing se. content but mainly about the writing (am I really visiting the right forum?)
3. The depiction of the character traits of Pseudo and Holly were done quite well, including the drawings and the arts (the backgrounds not so much...). There were some inconsistencies with Pseudo's character during the story, however they got (somewhat) explained at the end with "the voices"...and that wasn't executed very well.
4. Here and back at Steam there are some of the opinion that the writing is terrible. For me this is not true as the writing flow itself is rather genuine and seems like real talking (with actual feelings behind it) most of the time.
Regarding the story itself: I guess it depends on how much you're willing to immerse yourself into and go with it. Essentially, this is not a story about a nowhere girl (aka ghost) but a story about a nowhere direction of your life, where you just go on and on without a real purpose, hoping for things to change in your direction while they actually change away from you - and without you. Until you make a stand and go for the one thing that really matters to you, not regarding the costs...and this is where the story got me as I saw the truth in it...
The "good" ending did subvert my expectations, but it was the good ending nonetheless because they both wished for it to happen...be careful what you wish for... ;-)
Many thanks to the devs.
