Oracle Inside looks innocent when it loads in the browser. Cute island, simple UI, it almost feels like some chill summer adventure VN you’d open on your phone while waiting in a line. Then the pirate ship hits the rocks and suddenly the whole thing turns horny, messy and weird in a way that actually fits the story instead of just throwing tits at your face for no reason. You’re this young farmer guy who’s never seen much of the world, basically raised on potatoes and chores, and in one night he goes from “dad, I’ll feed the chickens” to “why is this barely dressed stranger talking about oracles and magic and also staring at my crotch like it’s part of the prophecy.” It’s not subtle. The game just leans into that awkward “first time touching real skin that isn’t yours” vibe, with the MC trying to act like a hero while clearly thinking with his dick half the time. The humor hits most of the time too: one scene where he tries to give a very serious speech about destiny while hiding a boner behind a bucket actually made me snort-laugh, even if the animation for that bucket clip is hilariously stiff, like someone coded it in a hurry on the bus.

What I liked as a tech nerd is that it actually runs smooth as hell on mobile. I tested it on a mid-range Android (Pixel 6a) in Chrome and on my old iPad using Safari, and it behaved nicer than a lot of “big budget” porn VNs. No random audio desync. Quick saves don’t freak out. Text transitions are fast, no ghosting between scenes, even when you hammer skip to replay that one blowjob scene with the storm still roaring in the background. Touch zones are big enough that you can play with one hand, which the devs absolutely knew. They tease a lot with angles too: partial nudity, wet clothes plastered to bodies after the storm, those little pauses between lines where the camera stays a bit too long on thighs or cleavage. There’s this moment on the beach where the MC is helping a soaked pirate girl out of the water, and the framing keeps “accidentally” cutting her face so you only see lips and chest and the curve of her ass while she jokes about teaching him “more useful hand skills.” It’s cheap, but it works. I just wish the text auto-advance speed slider actually remembered my setting between sessions, but apparently that’s asking for too much from the gods of horny optimization. The whole “oracle” part brings in some light fantasy flavor, a bit of “is this magic or just bullshit to get him naked faster,” and the AI-like prophetic voice that talks in his head at random times is weirdly hot when it starts commenting on his arousal like some pervy inner narrator. And then suddenly the game throws a quiet romantic campfire scene at you, with soft, clumsy kissing, like it remembered it’s supposed to be about feelings too, not just getting the MC’s farming tool wet. It’s chaotic, unpolished, sometimes cringe, sometimes genuinely sweet, and I kind of loved that it never fully decides if it wants to be a horny comedy, a fantasy romance, or just a porn VN pretending to be deeper than it is.

Dan is that guy who thought getting into automation engineering would make life all clean and logical, then ends up resetting routers for boomers on tech support while his dick basically runs his decision making. Game starts pretty calm, him just being this slightly awkward dude at a soul killing job, and then boom, Christina walks back into his life. Old high school friend. The kind of “friend” you used to think about in the shower and then tell yourself it was just hormones. Now she’s grown into this walking temptation with huge tits, soft voice, and that mix of sweet and lowkey horny teasing that makes your brain lag like a shitty Discord call. The game really leans into that familiar energy, that weird nostalgia where you remember her as the girl eating fries in the cafeteria, but now she’s pressing those big boobs against your arm and asking if you “missed hanging out” with that innocent smile that is absolutely not innocent.

It plays like one of those slow burn visual novels where half the tension is in what you don’t say. You’re clicking through their chats, coffee meetups, small talk that clearly wants to be dirty talk, and the fun is in trying to read her mood from each CG, each little facial shift. One moment she’s joking about your boring office job, next moment she’s leaning too close, t-shirt pulling just enough to show cleavage that should be illegal, and you get that CG freeze of her looking up like “what, do my tits distract you?” And yes, they do, thanks for asking. There are scenes where she pretends to be all innocent, like “oh, I didn’t know this top was so tight,” while she very obviously knows exactly what she’s doing. That teasing is almost more intense than the actual hentai scenes. Almost. When you finally get those, they’re the kind of CGs where you stop clicking and just stare. Sweat, flushed skin, her legs spread on your couch after “just watching a movie,” and you can almost hear the cheap Netflix show still playing in the background while she rides you slowly, hair messy, cheeks red, tits bouncing while she tries to “keep it quiet.” Yeah, that whole “friends” thing does not survive very long.

What stuck with me is how the game sells that romance angle without pretending it’s some pure love story. It’s horny as hell, but it’s not just random fuck scenes thrown at you like a porn hub playlist. You get that build up: old memories, little jealous moments when she mentions other guys, the way she casually touches your shoulder then pulls back like she’s testing you. One CG where she hugs you from behind after a rough day and her boobs are basically wrapped around you like a warm anime pillow, and you can tell she knows what that does to you. They talk about stupid stuff too, like high school rumors and who dated who, and in between those lines you feel the “what if we had hooked up back then” tension. At some point she straight up asks if you ever had a crush on her, and depending on what you pick, the vibe of the next scene totally shifts. There’s this moment where she shows up in your place “just for a drink” in tight jeans and a top that can barely contain her chest, sits way too close, then starts playing with her hair, crossing and uncrossing her legs, throwing you looks like she wants you to fuck up and make the first move. When you finally push past all that and she lets you strip her, she still keeps that teasing energy, like biting her lip and pretending she’s shy while her body tells a completely different story. It’s messy, it’s horny, it feels like that dangerous zone between old friend and full-on girlfriend, where every choice might fuck things up or make her moan your name louder. And honestly, that’s exactly the fun part.

Okay so first thing - Clara's transformations are absolutely wild and completely caught me off guard. I mean, I went in expecting some standard dating sim stuff with childhood friend Nala moving in, maybe some typical romance routes, but holy shit when Clara starts appearing... her body changes are genuinely unsettling in the best possible way. Like, we're talking complete physical metamorphosis that made me question what I was even looking at. The AI-generated visuals actually work really well here because there's this uncanny valley effect that makes her supernatural presence feel legitimately creepy. I spent way too much time trying to figure out if there was a pattern to when she'd show up, and honestly the randomness makes it worse in a good way.

The desire system is pretty straightforward - you build up points with Nala through conversations and choices, unlock new outfits for her (and trust me, they're worth it), but the real hook is how the game constantly pulls you between moving forward with this sweet childhood friend setup and getting dragged back into trauma with Clara. Alan's just this regular dude stuck in a dead-end job, which makes the supernatural horror elements hit harder. One minute you're having a normal conversation about breakfast, next minute Clara's there looking like something from a fever dream. The affinity tracking gets complicated because sometimes being nice to Nala feels like betraying Clara's memory, even though she's literally haunting you.

What really gets me is how the game doesn't let you forget about Clara even when you're trying to focus on Nala's route. She'll just appear during intimate moments, completely transformed, and suddenly you're dealing with guilt and supernatural terror while trying to romance your childhood friend. The big tits and ass tags are definitely accurate for Nala's scenes, but Clara's transformations go way beyond normal proportions into genuinely disturbing territory. I keep going back trying different dialogue choices to see if I can somehow save both relationships, but the game seems determined to make you choose between healing and obsession.

Kohei comes back to his old town for something boring like university, and instead walks straight into the kind of summer that fucks with your head for years after. It looks harmless at first. Childhood streets, cicadas screaming, cheap fans pushed to their limit, that older girl next door who used to ruffle his hair and laugh too loud. Misaki feels like she should be safe territory, familiar, almost family, this cozy fantasy of “onee-san who waited for you”. The game knows that expectation and plays with it in a way that’s honestly pretty mean. She’s still teasing, still bright on the surface, but her eyes slip away at weird moments, her smile freezes half a second too long. Small details like that. You pick a flirty choice, she laughs, leans in, you can almost smell her sweat and shampoo mix, and then some other guy’s name casually comes up and your stomach drops. It’s not subtle, and it’s not gentle.

The horny parts grow slowly, like mold in a corner you pretend not to see. At first you’re just choosing where to spend a day, which cheap cafe, whether to help her carry groceries. One scene you’re alone with Misaki in her apartment, the sun too bright through thin curtains, her in a loose tank top and shorts that ride up when she sits cross-legged. She offers you iced tea, your hand brushes her thigh when you take the glass, she goes quiet for a second. That silence is hotter than any moaning later. The game loves those tiny pauses, the routes where nothing explicit happens yet are somehow dirtier in your head than the straight-up sex scenes. Then there are the runs where you lean into the NTR sickness on purpose, like poking a bruise. Letting her reply to that late-night message. Choosing not to follow her when she “just goes to meet an old friend”. Coming back to a half-buttoned blouse, a faint smell that is not your cologne, and a CG that stings more because she is still smiling at you like she wants to protect you from what already happened. It gives you options to avoid that, sure, to keep things “pure” and romantic, but you feel the game secretly smirking when you pick them, like a producer forced to include a vanilla route to keep the sponsors calm.

What makes it interesting for me as a genre nerd is how it plays with POV shifts. One route you’re stuck inside Kohei’s head, rationalizing, pretending it’s fine, one bad choice, no big deal. On another, it flips and suddenly you’re watching scenes where you’re not supposed to be present at all, getting that ugly voyeur thrill. Sometimes you see Misaki from another guy’s eyes, the way he studies the sweat creeping along her neck, the way her body reacts even when her voice says “we shouldn’t”. That’s where the eroticism goes from simple horny to slightly cruel, because it forces you to admit that her desire is not a thing you own. And still the game offers proper romance lines, soft endings where you manage to hold on to her and build something tender out of all this mess. Those paths feel almost suspicious, like you wandered into a different title hosted on the same site by accident. But that contrast gives the sex extra charge. A slow kiss in a quiet room means one thing when you trust her; the same CG, same pose, after you saw what she did in another route, becomes loaded with paranoia, with “who touched you like this yesterday”. It is not elegant writing, not “high art”, but it understands really well how lust, jealousy, nostalgia and that stupid first-love hope all bleed into each other and make you click “next” even when you already hate the ending you know you’re walking toward.
