5/5 lovey-dovey . Extrememly well made animations, good system and gameplay, enjoyable story. Vivid and detailed description on how the heroine developed an attachment on the protagonist. One of my personal best in 2025. The game could benefit from more choices of clothes and scenes.
The game doesn't work, it stops randomly with a CG and some background music playing and nothing to do, no text, nothign to click to progress the story. It looks good, the presentations is good, but sadly it doesn't work. Thats about it, really. I don't have problem running other unity games on my PC, so this is on devs side.
The initial presentation is worthy of 4 star, the animation physic is smooth and small detail like sweat droplet really add to realism. But that's all for the initial, from day 3 and onward the game become caressing simulator with no restraint that should have cause skin burn. I suggest not to care about the story or dialogue, because making sense of them is truly vexing, they aren't people but bumbling rejected Shoujo couple from alternated timeline. Full discretion advice, if bedding minor isn't your kink, like teacher and student relationship, I would suggest staying away from this one. Despite being the adult of the relationship, you're not in control and the heroine creepily proactive to the current circumstance.
a very good touch game with 2d animations. short if you skip the dialogues, since there are 5 CG and 5 scenarios. and it's even dubbed. the only problem is that in some scene the body has weird proportion
I absolutely love this game. The animation is a solid 10/10, and the touch/feel mechanics are among the best I’ve experienced. The main character is adorable and genuinely endearing. Relationship-building is well-paced, not too fast, not too slow. The sex scenes are well-executed, and the character controls feel smooth and responsive. But I want more . The game is incredibly good, but it feels too short. There are so many mid-tier games out there that take up a ton of storage for no real reason, and i think this one deserve more contents(more scenes, positions, locations).
This game is quite something. The Live2D animation is incredible; the characters move so fluidly, it almost feels like they're right there. The character designs are also very cute . Plus, the story itself is surprisingly sweet and heartwarming , making for a genuinely enjoyable experience. My only quibble, and it's a minor one, is the mosaic censoring . It can be a little distracting sometimes, breaking the immersion. But overall, it's a lovely game.
One of my favorites of these live2d interaction type games. Lots of events day-to-day and great design and artwork. The interactions move a little fast for my liking, its not as slow burn as i want but thats ok
It's a good hentai game. Meet and get along with a cute otaku girl within 30 days, so on and so forth. I don't want to spoil anything, so I won't mention the endings. Notice how I said it's a good HENTAI GAME, not a good GAME, well, it's basically an interactive visual novel / video, one you can give headpats, touch certain body parts and etc. The gameplay is really lacking, and it gets repetitive and bored very quickly. Outside from new dialogues and outfits, once you get to the ecchi stuff, there isn't really much left to explore. If you only care about the nsfw part, it's a 5 out of 5, but for me, it's a 4 out of 5.
One of the best vanilla touching sim game Would've been an easy 5 stars if not for the piss-poor MTL and formatting. This game is one of the best touch sim game I've ever played. The FMC is such a qt. She's got the right level of thiccness. The MC isn't fat or a lazy ass. And the art style is damn cute. Hell, the VA is good too. Gameplay isn't too grindy or mundane. You unlock different interactions and scenes as you progress through the game and she slowly falls in love with you. It's such a shame that such a great game has a bad MTL. I hope this comes to Steam with a proper English translation and I would easily replay this
This game is truly excellent. I've never played any eroge with this level of intimate player feedback and believability. Her expressions with every interaction, from the heavily exaggerated breaths she makes when you pound her to sweetly subtle smiles she does when you give her a kiss, really sells the emotion she's conveying. The way the physics are handled have the perfect amount of weight; not too much jiggle that it looks stupid, not so stiff it doesn't feel like you're watching a paper doll writhe on screen. Hell, even the simple act of clicking and dragging is so fined tuned that it feels like you're really moving or rubbing whatever part if her you're holding. The devs put so much love, care and detail into how everything in each scene moves and flows. You're not clicking menus to play canned scenes, there's no sliders or "fast/medium/slow" buttons that just speed or slow a premade animation, it's got none of that. It's YOU, yes YOU, the player, who has proper control in every scene. Even though there's not many different scenarios, the sheer quality of each interaction makes up for it. If we're talking objective downsides, there's a few I can pick out. The story isn't really compelling at all. You're a teacher and end up fucking your cute student and sex ensues. The perspective in some shots, like in the bed scene, seems a little odd sometimes. Mostly due to the fact that it's a 2d rig trying it's best to look believable. Last is the fact that it doesn't have much fetish content. Most it does is like, massages and groping along with a few outfits, but that's it. That being said, you should 100% give this game a try simply to experience what a game centered around manual control is capable of. It might not have any outlandish or highly specific content, but it's unique systems will certainly get you interested in it's potential. If you're a vanilla lover like me? This shit is nearly perfect. It makes me want more in the same way base Monster Hunter games make me want more content, and that's saying something.
The game leaves an overall positive impression. The art style is absolutely beautiful and creates a great atmosphere. The animations are decent, although they could feel a bit smoother in some places. Unfortunately, there aren’t that many different scenes, which is a bit of a shame, but despite that, it’s definitely worth giving the game a try. One of its biggest strengths is that it’s not overly long or grindy, so you can fully enjoy the experience without feeling bored or frustrated. If you're looking for a short but enjoyable game, you should absolutely check it out!
one of the best touch and feel eske games ive come across, really smoothe and to the point, not cluttered with dialogue and sweet in a way, just play it you wont be dissapointed, only gripe with it is the lack of updates, its a finished game but a DLC or 2 would be nice
Enjoyable game with a few different options for advancing the game's storyline. Pros: Decent enough graphics, nice animations, a branching story, decent rate of advancement. Cons: A bit repetitive, some minigames can be annoying at times, starts slow.
Love this game, the game give you multiple choice in term of actions (well at least at the end of the game, you can do it automatically aswell as manually) the fmc is also really cute, and we grow really attached to her while playing that game
I loved this game so much! it is so wholesome and the girl is so cute, the touching sim is so detailed probably one of the best in my opinion, I would love more games like this. Only flaw is the MTL translation but I don't mind since I understood what the errors meant. 10/10 peak game.
One of the best "touching" sim i have ever played. Tbh, im considering this one the "best" for me, because i cannot think of any game on this genre that can top my experience playing this game. The heroine reactions and development is really cute, the interactions make me go mokey mode many times. (uga boga stuffs) I really recommend this game if you like trying touching sims, and cute heroine with amazing expressions.
If you like games in the touch and feel genre, or games where you use your mouse to fondle and have sex with the heroine, then you will want to give this game a try. This is a masterpiece in that genre and one of my new favorite adult games. Touch and feel games depend on great art and animation above all else. If you grope the heroine's tits and it's animated in a wooden and stiff way, then you might as well uninstall the game right there. Thankfully, this game excels in both fronts. The art of the heroine is phenomenal. What makes the art of her stand out compared to most other anime games is that her body feels convincingly soft and supple due to what seems like a layer of fat over her body, as if it were like an actual and real body. The animation and use of Live2D is among the best of the best, rivaling or even surpassing some of the best in the genre. When one fondles the heroine's boobs, they move in ways that make them look like they have actual weight. If there were not enough, there are multiple sex scenes, positions, and outfits, which are more than enough to satisfy someone for the approximately 2-hour play time, which is more content than the other touch and feel games with this same level of quality. The actual story is pretty generic, and I was able to get through it with my basic levels of Japanese. It's not too important to understand. She's the typical rich girl in adult games -- sweet, seemingly innocent, cute, and sexy, but as the game progresses, she's revealed to also be very horny and willing to wear all kinds of lewd outfits for the player's desire. The only other games I've found of this quality in this genre either contain loli characters or have a lackluster story and sense of progression. I think this stands out in a good way, and deserves a higher score than the one it already has.
Very sexy character, well animated, nice scenarios. Only complaint is some weird performance at times. It could've used a few more animations but pretty good overall. Nice pace without feeling too grindy.
It's an excellent little game. It has more content than most games of its kind nowadays, and personally, it leaves me wanting more. The story is well paced and the animation is fluid, although The translation is trash and there are some inconsistencies in the girl's design between scenes.
This game SEEMS good, like really good but i rated it so low because the MTL is so dogshit i genuinely have no idea what's going on or what i'm doing. Not to mention it loads so goddamn slow too. this is hands down one of the worst MTL's i've even seen which is a shame since this game seems fun. i'll come back to it once it gets a better translation and so should you.
