Right, been playing this for a bit now and while I haven't finished it fully, figured I'd drop some thoughts thus far.
Characters are pretty well written, the renders look good and the concept, while not exactly new, is pretty well done in terms of an AVN. The flashback switches between different timelines (realities? dimensions? I don't even know honestly) is pretty jarring as you don't really have anything that gives you any semblance of narrative direction, moreover it's just also difficult to know what fits where or if it's even a reality and not a figment of imagination, but it's not enough to really make or break enjoyment, just that a bit of extra hints as to exactly what/where/when things are going on would probably better narratively convey what you want to convey.
Now, that being said, I personally REALLY have a pet peeve in regards to dishonest characters, manipulative characters and the whole deus ex machina trope where the MC is helplessly caught in the middle of a shitstorm with no player agency outside of just sitting and watching the trainwreck happen, which this game kind of employs a lot. I dislike basically all of the characters besides maybe Chloe, Xue was almost palatable but the whole 'braindead horny to an almost rape degree' is a bit much. I thoroughly dislike both Selene and Ashley, hot damn those are some trash characters (but again, they're written well, if they weren't then I wouldn't have such a visceral reaction).
Overall, it's definitely one of the more wellmade games out there though I don't think it's for me, too many things that I truly dislike. Keep at it though dev, it's clear that you're talented at what you do and it'll be interesting to see what other games you can pull out of your sleeve.
