I downloaded about 20 interesting looking romance visual novels without reading any summaries or comments. I've completed 5 of them, with just having finished Adastra tonight after about 10 to 15 hours total playtime (was hard to keep track of time, but this game is realllly long. I actually looked into it and this VN is about the same length as the first Lord of the Rings book.)
I just want to preface by saying I don't identify as a furry. I don't really know anything about furry culture, but Adastra is by far the best romance visual novel I have ever played in my entire life. The relationship with Amicus is probably the best-written romance I have ever experienced in a video game. The climax and conclusion made me sob harder than I've cried in quite a long time. I'm still quite shaken and am very sad that it's over.
All of the visual novels I've played usually follow some sort of formula. Like a lot of little choices, you choose your romance branch, and the story is fairly short. Adastra isn't like that at all, it's literally just a full-fledged novel that's put into visual novel form. My two small criticisms would be there there isn't really any transitions going from one "act" or "chapter" to another, it's all continuous, so you are sometimes forced to take breaks at awkward moments. Also at times, the pacing can become a little too slow and exposition-heavy. But these are pretty minor criticisms.
In fact, this game was so amazing that I'm scared to play my 15 remaining games because I'm scared that they won't be able to reach this level of quality.
