I will be completely honest: I didn’t really liked this visual novel.
As far as I understand the main draw for it is Amicus, and I didn’t really liked him. I connected with him somewhat during the course of the story, but then he threw Marco under the bus by sending him back home with an impossible mission and with no help from his side whatsoever and I lost all sympathy for him, as well as all of the interest in all of its sequels and supplementary material…. Althought it isn’t that much of a problem considering that all of it stuck in development hell.
On a side note I really didn’t enjoy any of his nsfw scenes with Marco. They all were a bit too rapey from his side for my liking.
