I created this account for the soul purpose of writing a review (On second thought it is now more an Essay) on this game and it is amazing. So, far I have only completed the Alone route and I'm working my way through the Keisuke route so what I'm saying is mostly based off that, the shortest route so far (Unless you count the Mum route, which I have also completed) and it's gotten me this interested in the game.
When I'm looking for an erotic game one of the main things that I'm looking for is a great story line and the characters choices making sense for their characterization thus far. This game delivers on that and more with every decision and choice the protagonist makes based off of their choice's despite being accidental Zack makes himself into Zoey and as AI states that he has made himself who he wanted the most something impossible made possible.
*Spoilers for the alone route which it is easy and the quickest route to complete, so do it
The story has been amazing so far and I love the mental side of things explored in the Alone route. I was mostly skimming through things but I thought I got the main ideas. But the next day something struck me about the route I completed (This might be wrong entirely but if it is my interpretation of it and it got me thinking about it for a few minutes instead of working on a big project I have). Zoey as you're playing as her throughout it is being hunted by this shadowy mist then she meets Haze and he's not being effected by it. I didn't think much about it, but then all the mental implications of this entire scene hit me. The mist represented the subconscious of Zack. It blew my mind when I realized it (again it might of been stated in game but I might of missed it).
Zack throughout his entire life has been trying to hide his female side and has oppressed Haze who used to represent those emotions due to it but now his masculine side is becoming less dominant but he still has this subconscious defense mechanism against it to try and not show his true self. But this backfires as when he does becoming female and his feminine traits start showing more and becoming the majority he dreams of himself with those traits and the mere fact that he is already dreaming himself as female really shows how adapt to the concept of being a women he was prier with it not seeing the light of day until now when his feminine traits have become more prevalent.
The story of Zack/Zoey's mental health is one that should be brought up throughout the story and with many other lewd games they don't consider what the mental effects of putting characters in positions like this are. Here's an example from another game I played with a basis of the protagonist being a male and ending up as female which, the mental health of the protagonist hardly got mentioned and when it was, it was just after the transformation and didn't heal it properly. This annoyed me, the lack of care to the character's writing but the game was still interesting from the world building.
Haze being unaffected is another main thing that drives the subconscious killing off his feminine traits thing through. Haze has probably been through the same pain that Zoey was in for less than a second for the majority of his existence but he is still willing to help out the main cause of the pain. But the fact him being around Zoey blocking off the detection of the mist as Zack/Zoey's masculine traits decrease while the opposite is true for Haze with the masculine traits wording off the mist as it has always done is just amazing writing.
The Mist as I mentioned prior represents Zack's subconscious with it being created undenounced by Zack as a suppression method for his feminine side. This self destructive mentality, if never realized would of lead Zack to an absolutely miserable life where he would of never been able to express how he really feels without harming his mental health.
In the end Zack/Zoey are complete again which comes with the disappearance of Haze as he has completed his purpose, to make Zack/Zoey be their true self. This results in the destruction of the subconscious hatred that Zack felt for himself and truly accept that he has become Zoey and if he didn't it would of lead him down a darker path.
TLDR, this game has an amazing representation of ones mental health when faced with becoming something you repressed your entire life.
Thank you for making this game and even if it's not at the front of the priority's list I hope for a continuation on the Alone Route.
