The story itself wasn't bad and most characters were likeable (including the "villain(s)" – if by villain we mean Kaiden (and Gale) and not Dio ^^ –, which is interesting). However, the story is really poorly written (in terms of grammar, not style); there are (really) a lot of grammar and spelling errors, which makes it clear that the text hasn't been proofread or even just simply re-read after being written. Unfortunately, that alone makes it not worth its (very) high price (I wouldn't make a comment if it was a free game, or if there was just a mistake here and there, but that wasn't the case here).

There is also a problem with the "skip" function, which sometimes doesn't function properly (sometimes the same characters say the exact same lines in different routes and it still refuses to skip those parts); on its own, it's a minor detail, but I'm signalling it just in case too. There are also five spaces for LI, which might lead players to believe there are five routes, even though there are, in the end, "only" four (it's not a problem that there are four, but then maybe there could have been four spaces instead, so as to not confuse players? Just a thought).

Finally, in terms of content, there were some problematic stereotypes that bothered me (and that made one of the routes not enjoyable for me). Of course, since it's your story, it's your absolute right to use those stereotypes if you want to; I'm just giving feedback based on my experience. I also think a content warning for the torture descriptions could have been useful/nice; I'm usually okay with violence in games, but that part was difficult to read for me and I personally wasn't expecting it.
