Version 0.9b
"Twisted Memories: An ugly bastard turns back into a teenager and corrupts the women of his past" is the most factually correct and yet misleading title I've ever seen in an adult game. Factual in the sense that it summarizes the plot succinctly, but NO... this game isn't about a horny teenager going around to take revenge on girls and having a fuckfest shtick.
Story
You play a loser in his late 40s who time travels back to when he was a high school student and gets a new opportunity to turn his life around. Yes, it's a harem game and there will be sex with many girls, but what sets TM apart is the emotionally intense and compelling narrative - we experience it through MC's anger, regret and introspection when he relooks at the people around him and the decisions he made in the past.
This isn't a game about an old pervert going around blackmailing and fucking every woman he sees. The developer spends considerable time dwelling on MC's pre-time travel relationship with these women, how he sees them differently now and how he would like to take his interactions with them going forward.
The emotional intensity is even stronger if you choose the seduction route for all the main girls. Though a harem game which by definition limits its realism, the developer pushes the envelope to be as realistic as possible for this genre, i.e. the gals don't just automatically jump onto MC's cock and accept him sleeping around.
In fact, out of all the LIs, only Lola fully accepts MC starting a harem. The rest range from partial acceptance, reluctance to outright rejection, so it can be quite comical to see MC trying to juggle all these conflicting LIs who don't see eye to eye with each other often.
Game Mechanic
Visual novel with choices that allow you to pick either a seduction or corruption route with six main LIs and a yes / no choice for another six secondary LIs.
The different routes mostly affect the type of sex scenes and some character specific events. Corruption routes are generally enjoyable as expected, but it is the seduction ones that truly shine. The latter also gels with the overall narrative better IMO.
One point of note is seduction route isn't pure romance per se, it still has elements of corruption within, just less pronounced.
Background / Character Renders
Background and character models are made with HS2 with adequate post processing. The character designs slant towards the anime kawaii end of spectrum with big boobs and MC features a monster dick.
Character Development
Old man either time travelling, dead soul takes over a young body or isekai into a young character etc. are common in AVNs. Most end up mediocre because character build up sucks, you don't get a sense these MCs are old souls - they behave like a typical horny teenager which defeats the whole purpose of the starting premise.
Not TM though, our MC here thinks and reflects a lot when going through his new life here. He deals with matters like an experienced hand whether it is in everyday situations, handling relationships or corrupting the ladies. Players are constantly reminded of the fact that MC used to be an old guy now with a new body and perspective. Very refreshing take on this genre.
The LIs are varied and distinct in their character, some might be a bit tropey while others less so. Some are more predisposed to liking MC while others are more slow burn to turn their relationship around.
Sex Scenes
In terms of pacing and quantity, it's a good mix evenly spread out across gameplay. Some like Stephanie and Emily are positive with MC and have sex scenes pretty early, others take a while to materialize and as of V0.9b there are still several LIs without any or with only limited lewd scenarios.
Scenes are top notch - the build-up is lengthy, varied in scenarios, backed by titillating dialogue, sound effects and music. Posing, camera angles and animations are professional and well customized instead of the usual HS2 defaults.
BGM and Sound Effects
Diverse BGMs are appropriately curated and compliment the story from tense to emotional to funny moments while non-sex sound effects are minimal.
Conclusion
I wasn't expecting to be that emotionally invested starting out due to its misleading title, but TM turns out to be a gem. The story and the characters are deeply immersive; MC's rebirth is emotionally resonant and thoughtfully developed and I like how has to put in effort to convince the LIs to accept a harem with mixed results; a delightful departure from the usual zero effort harem fest.
The sex is top notch and there is some player agency without making the branching too complicated to handle. Only point of improvement is the text in certain updates lacks QC and spelling and grammar errors are sometimes too frequent to the point of being distracting.
