What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
It pains me a bit to have to write this since I looked forward to the release, Starting with the good: The main game play is pretty fun and challenges you to balance risk and reward by asking you to gamble by being aggressive to make progress. The writing, while not compelling, is enough to establish a connection between the characters. The 3D sex scenes are pretty good though limited in their scope. Now for the bad: "Pretty good" and "good enough" seem to be the entire design philosophy behind the game. While there are multiple sex scenes and positions you can switch between, they lack any customization only allowing you to turn on or off the same animation loop that only changes when your character "finishes" but not when the female character does. Further more I'm fairly certain all sex scenes use the same moaning audio on loop. Then there's the issue of play time. As you can see, I have 2.6 hours on record which was enough to unlock every scene and easter egg. Steam allows you to refund a game if you have less than 2 hours of play time in it. There are several, seemingly, deliberate design choices made to pad out game time such as requiring you to finish each stage…20 found this helpful
I wouldn't say that the game is "bad" per se, it's just not good enough for the money. For 20 bucks I can get tons far better games with more content - completing the main story in around an hour is simply not enough. Yes, there's more content to unlock in the "inferno mode" but that just seems like a chore. Sadly, the basics of the game are fine and I was considering giving the game a positive review, but in the end, it just didn't convince me. If they'd put more levels in and at least some variation to the grind it would be fine. A shame, I do like Mio and I do want to like this game, I just can't. If they were to make a second iteration of this game and give it 3 times the effort (and content) then we'd certainly have a banger.7 found this helpful
don't have a real story, CG are just some not moving images, each scene are just 1 animation repeatedly, , the char in scene don't even match what it expected to show in the image when climax, don't show any emotion Dev too lazy, they only add a image to show char emotion when they can add that emotion directly to the scene. Mini game are just some random thing to do to waste time, don't have any meaning in story6 found this helpful
Would not recommend. Tea Egg minigame is bugged and impossible to win. Will reverse if Dev makes minigame win-able.5 found this helpful

[/quote] [h2]Summary[/h2] [quote]Patch is not required![/quote] [b]Sex Trainer's Diary: Hidden Kink[/b] is a 3D SLG eroge about fulfilling clients' unusual fetishes. Besides its 3 main story stages (2 difficulties), the game also features 2 extra open world maps filled with meme-filled quests and a bizarre bird shooting minigame. There is even a hidden quest that transforms the protagonist into a woman (with a H-scene!). Unfortunately, it is hard to get past how short the main story is. While the game does not offer many H-scenes (5+1 sets of interactive H-scenes, 7 static H-scenes, and 5 ending CGs), their quality is decent. The game currently only has Chinese voice acting but Japanese voices. Players who care about this should take note. Overall, the game's quality is solid enough, assuming the short main story isn't an issue for you.
