This is probably the best simulator I've played. It's short and sweet. There are a lot of games that try to stick this kind of simulator into a VN or RPG, dragging you through 5-10 min of dialogue/chores to get this kind of simulator "mini-game", but you don't have the "skills" to perform well enough in the simulator until you do the same grind half a dozen more times. This was a refreshing lack of bullshit. Maybe spoiled me a bit. I want developers to put more effort into these kinds of scenes instead of the "barrier-to-entry" game that comes before the porn. Your sister is home from school. She wants to sit in your lap. You're getting busy with her, and she wants it. Straight to the point, doesn't overstay. The artstyle is good, and they put great deal of work into her reactions and dialogue for every little thing. The split view of her face and what you're doing is done very well. As the meter for her climax rises, and as the scene drags on, her mood/face/responses/rear-view change appropriately. When you get past the initial "warm-up" stage, you're able to talk dirty alongside every action, getting different responses on the same option the more heated she is. The only dropped-ball I can vaguely complain about is there's a tracker for if you're finding all the dialogue. There's no rewards for the tedious task of maxing out all the percentages. Maybe that's for the better. Very much looking forward to any of their future creations.
Description is misleading. It comes across as an "Imouto Life: Monochrome" clone when it's actually more of an animated manga with no real gameplay element aside from osawari. My problem with this one is the fact that the sister seems innocent and oblivious to sex in chapter one, where she sits on Onii-chan's lap to play games, only to receive a complete retcon in chapter 3 where they reveal she's actually a slut with previous sex experience. This really kills the "pure love" ending that they were going for in this one. Chapter 3 should have been a defloration scene in order to justify the chapter one innocence and the pure love ending.
Hey. Honestly, this game is just that good. It deserves 5 stars easily. Although it's a short game, every minute playing is worth it. It's exactly what it needs to be for a hentai game. You get straight into it, the progress is smooth, linear, but it still feels like you are actively engaged at every step of the way. The game has surprisingly lot of content to be found by the player, it's fun to experiment. Sound: the game doesn't have any. But it's actually better. You don't need to listen to cumming screams every time she cums. It can get annoying rather quickly in the games with sound. You don't have to work long and hard for a game to give you H. It's right there from the start. But, somehow it doesn't feel unrealistic or like it's too fake. It has feels. I especially enjoyed the dialogues in the last sex scene. They are just precious. Totally recommend. TIP about unlocking all the content: If you want to unlock all the content you have to make all the actions in all possible scenarios. Even the bad ones. Example: Try to massage tit, while pecking on the neck while trying to touch pussy too early so she pushes you away. Then try same while playing with nipple and not pecking the neck. DO EVERYTHING you can at every point and check the progress bar. At some point it can increase by as little at 0.1% at the time. I got 100% in this way after it was seemingly stuck at 90- something %.
Simple but great game. Its a game where you touch your sister to make her horny then eventually have sex. Nothing revolutionary of fancy but well executed. Art and progression is good. There are 3 and a half scenes. I say half because the first one is basically two parts where you slowly arouse your sister to do more intimate things. Story is nothing to right home about but it is fine for what it is. The only weird thing is that there seems to be some sort of system for progression or seeing all the dialogue but it doesn't seem to change anything according to what some other person said.
Unga Bunga Translation: "Short but sweet is the best way to describe this game. It's a linear story, almost if not a visual novel kind of progression. - Gameplay Just a click it and wait pretty much, again it's just a matter of patience and clicking when it says to continue. - Storyline Super linear and simple, sister comes home and you end up seducing her. Like I said it's short and sweet and to the point. - Content 3 major scenes: Touching and stripping, sixty nine with what looks like you could go on until your satisfied, and cowgirl with the same going till done. - Artwork Really nice and clean. It's not over the top and it's done in a way that is like an animated hentai manga which works really well for it. Most who do this don't make it as smooth and appealing. - Overall Def enjoyed it, though my only gripe is how long dialogue takes without any skip or going at my own pace kind of options. The small window as well was annoying but not a big concern. And with how short this was it's one of those if you were to pick it up again it wouldn't be crazy long to finish it again. Didn't see a gallery or anything but by the time I had gotten to the credits I was pretty much done with playing so I'm not sure if it offers it upon completion or if you can skip through dialogue after. Either way pretty good and hope to see more, maybe even larger projects."
Big fan of groping/simple point and click games, and this one is pretty great. Only reason this doesn't get a 5/5 is no va, but even then, good nut. It has fairly simple animations, but effective enough where it doesn't look bad, though it's nothing crazy. Artstyle falls under the same thoughts for me, simple, but effective. However, it isn't trying to be anything special, hence it's 4/5. It might be a quick kum and go but I like it, would nut again.
The art is great, the storyline and dialogues are simple but they do the job, the translation is good but the bugs and glitches make this game nearly unplayable. It's almost like it was never tested, they just put this all together and threw it out there. Also, there's no gallery, so if you want to see a certain scene you have to go back and play the game normally.
Good animations, intuitive game play. Sense points button makes finding the hard to find clickables much easier(wish this was a real life function). Art style is between good and above average. Sound effects is in that same range. Would recommend for a quick wank.
Possibly the best game in this genre I've played, although I would have liked to see a gallery or free play of some kind.The animation is basic, but effective, and the art style is definitely something I like. The buildup of tension though is wonderfully done, it doesn't take very long to get there, but it isn't immediate either.
TLDR : Cute little incest game, pretty similar to some others in the genre but worth playing if you like these sorts of things. There is more of a "story" to this than most in this genre. Gameplay is pretty simple, you tease her and depending on her "state" or sensitivity level she lets it slide or stops you. You increase her sensitivity by harassing her until you convince her to service you and it continues from there. The game will stop your actions for story and plays fairly well but a little slow at times. The storyline is simple but actually pretty good. The dialogue between yourself and the sister girl feels pretty realistic and reasonable and it continues at a pretty smooth pace. There is not multiple paths, but the one you have is fairly interesting and the dialogue is cute. I think it stands out as being stronger than most teasing games. Art and scenes are pretty good, everything is animated though simple. The pacing can be somewhat frustrating at times as you don't have as much control over the sensitivity or the rate of arousal but it's nothing really worth complaining about deeply. Sound is fine, nothing too notable to speak of. It's pretty much exactly what the other games in this genre do. Definitely not meant to be a focus.
+ Good Concept + Good Characters + Good English ( despite MTL ) = Linear scene progression, but you can alter the scenes to your liking = Decent Art = Decent Animations = Incest ( brother x sister ) - Fast Pacing and Development [v1.0.1.2]
Half the actions just straight up don't work eg fondling the breast, fingering and probably more, but I didn't bother to "play" further. For what is basically a glorified flash game made with Unity it's baffling how buggy it is.
I was a very short but really good game, amazing visuals, smooth animation, 3 scenes with interaction, it even lets you know the % of completion of each scene after completion, it has post credits scene. Sadly it did not have voice over.
An incredible number of visual and other bugs for one short Unity game. Non-working buttons, missing body parts, or even the entire face. It's really cool to watch a faceless woman and a man without a dick.
Easy five stars. For MTL the dialogue is all very good. Not only are there no mistakes but it reads well and has a lot of character to it. The animations are excellent. They're not super smooth but it reads as a stylistic choice rather than a limitation and have a lot of detail and personality even with the low frames. The art as a whole is great, with some very nice attention to detail as the scenes progress. And speaking of progression- Honestly one of the best games in this style in terms of scene progression. The game doesn't linger too long on any one scene and has tons of little interactive elements that make the scenes feel dynamic. The girl will react if you push things too far, and will take full initiative in the second scene. The feeling of a 'race' in the second scene is honestly phenomenal and is a real standout. The final third scene is a rare treat of having MC POV and is very, very hot. There is a bug where it doesn't size up to fullscreen properly but that's the only thing taking away from it. All told this game is absolutely fantastic and is an easy and strong recommend for anyone who likes this style of touching games. It also doesn't use the normal 'good bar bad bar' format, instead just having a simple progression with no 'bad end' state that I could find. It makes it a little less complex on the gameplay side but more than makes up for that with the charm in the characters and the, again VERY strong, sense of progression and building lust within the scenes.
Great, has lots of different animation and positions. basically every decent touching black and white sim, but actually goes the extra mile and it's great. different positions can do different things, grabbing her ass with both hands changes the reaction, hugging her allows you to make out with her, or you can push her up to suck on her nipples or play with her booobs. highly recommended for those that like these games.
A nice little game that dives into the action fast. Basic gameplay but the art is great and the scenes are good. Apparently it's machine translated but except for one or two awkward lines the dialogue felt natural. I had no issues with animations or anything like that although other people did. Audio might as well be nothing though.
