◇30 Days of Slightly Thrilling, Naughty Moments with My Aloof Teenage Sister◇ Due to their parents' circumstances, a brother and sister end up living together for 30 days. The sister is entering adolescence, and though it's their first time living alone together in a while, she seems distant. They talk, interact... and sometimes try naughty little pranks. In their private room, the distance between them slowly shrinks... A sweet sister cohabitation life simulation!

This is some peak experience, even with grind, this game worth all of the wasted time. Absolutely better than many VN'like "3D" novels that are very trendy this days. The art is very nostalgic, animation.. Optimization is really bad idk why but on my amd gpu coils are whining like crazy on the night scenes. Overall 10/10
The progression speed in this game makes absolutely no sense and ruins the entire experience. This isn't a critique about the art (which isn't great,) or the H-content of the game, the game itself is just awful . Every upgrade you can do feels pointless. For example, the upgrade to increase Work Efficiency makes work take 14 points instead of 15, but you get points in increments of 3, so you still need to work the exact same amount until you upgrade it 3 times, which takes like 20 days of studying to accomplish. The entire span of the game is 30 days, and this assumes that you'll basically ignore your sister the entire time just to get this one upgrade while making zero money, and zero progress. Sure, the NG+ just wraps the game back around to the start and you retain all stats with your sister, but then what is the point of the 30 day limit? Whoever designed the actual game part of this game is a complete moron.
Hey. "I've tried it so you don't have to" - these are my feels right now. Played for a few hours and I think this is easily one of the worst game I've tried so far on this website. So far these are the conclusions: - art is shit - it really looks not good. - "adolescent sister" has porn-star-plastic-surgery sized breasts. Which are totally out of place and not appealing. They look like sagged boobs of a 40-something woman that were squeezed into a push-up bra to look like that. but those points are secondary. Real shit comes next. - PROTAG doesn't know the word efficiency. He gets paid once every 3 days. 7 k yen. Game is so out of balance that you will NOT have enough ENERGY to do almost anything (peeking takes stamina constantly too) you will not have MONEY to buy shit to boost efficiency either. - If you try to somehow boost your income, you will quickly notice that you simply don't make enough progress to be able to buy all the shit before the game's END. NOT TO MENTION YOU DON'T have time to spend on your sister that way. - there are lottery tickets that don't work. I thought that this is simply hidden item that will unlock the fucking money. WIN RESULTS were supposed to be announced every SATURDAY. Yet SATURDAY came and literally nothing happened. Did I win? Did I lose? Did I NOT do something to trigger this shit? IS this a BUG? I don't know! Item is still in my inventory. I CAN"T click it or check results in any way. I waited till Monday, thinking the fucking results will arrive later, but NO. Nothing. - you feel constant pressure that comes from impending game end. Days are ticking away yet you are simply not making enough money to cover expenses to buy fucking drinks or gifts. - exercising feels necessary yet wasteful at the same time. Because you're not making enough money as it is. All that shit could have been easily overlooked if you had say at least 3 months to live or even more. Like half a year maybe? Alternative way to play could be to simply talk to sister and not work or buy anything at all. But you will still need to exercise because you will simply not have enough MAX stamina to finish one peeking session. I can compare this game to another game. 30 days with my school-refusing sister. Which has NONE of the problems this one has. The only major downside that one has is there is not enough content. Yet everything that is present is masterfully done. Better go play that one instead. That one even has good replay potential, because somehow you don't get tired or frustrated when playing it at all, even of 3rd playthrough.
It's a completely fine "one of those" games. Graphics are fine, options are fine. Everything's fine! Game's pretty easy. Got a Normal ending, game lets you continue with your stats on another lap, and on the second lap I got the True ending. This is a 3/5 game made a 4/5 game because it doesn't pretend not to be incest.
Yeah, this is pretty tight. Both the gameplay and the sister. Joking aside, this is a pretty decent cohabitation game. My only real gripe is that grinding for stat increases is abysmally slow. Money comes in incredibly slow and stat boosts take up a ton of money which makes increasing your stats take forever. If you wonder what I mean, essentially, if you use the work option every day for 5 days, you will only get 8,000 yen. Meanwhile in order to get the first boost to your stat training from +1 to +2 takes around 10,000 yen, so around 10 whole days of working while you also try and boost your stamina so you can do more while also trying to boost your imoutos affection and lust. And if you do what I did and try to boost your working speed, it'll go from 15 down to 14 which takes the same amount of days(5) to complete, so you essentially just wasted all your time doing literally nothing. If you want a tip, just buy the first dumbell upgrade after the first paycheck and boost your stamina. That way you can potentially do two work options in one day, massively decreasing the money grind. However, if you're playing decently and get the good ending, you get unlimited days, so as long as you keep your affection grind going, you can take all the time you need. This is a game which rewards patience and people who love playing the long game will adore this one. Basically, if you like the monochrome sister cohabitation games, this one will be right up your ally.
Yes, this is yet another cohabitation game, and yes this involves sisters, because if youre gonna get a girl to suck your cock, theres really no better, and indeed convenient, target available for cohabitation in this world. So the premise is basically youre tasked to take care of your totally legal, school going sis for 30 days, while your parents abandon their responsibilities. She doesnt really like you, or even care so much to have a basic human conversation with her big bro, but after some strong effort on your part, you slowly worm yourself into her heart in a manner that is at least humanly relatable. Gameplay revolves around getting your stats up while lil sis goes to school, getting to know her better when she comes back, and the usual nightcrawling sessions. Your task is to get her affection and arousal stat up enough to open new H options. Sounds easy but its anything but, because raising any of your 4 different stats is like watching someone die from chinese water torture, not to mention that there is an implicit limit as to how much you can raise, as there is only 30 days and each stat point is gained after about 7 days of grinding. The H is basically consensual sexual assault via bath, toilet, and amusingly kotetsu. The non-consensual-ish H scenes is primarily from nightcrawling where you do the usual grope and later penetration. Theres no VA but there is slight animations. Artwork is serviceable, its not something that'll occupy your mind, but the games good enough that its not a deal breaker. Certainly for me, its not the main reason why Im playing it. To Conclude... My first impressions wasnt that great. The game is pretty much the same shit seen from other cohabitation games, but as I pass through the finish line, one thing stands out and thats the pacing is probably one of the best Ive experienced. The game is paced methodically to ensure that youre engaged with its mechanics throughout, so much so that every last bit of spare time is not wasted. You learn quickly to appreciate what little amount of time, stam, and interactions you have with lil sis because the game is relentlessly calculated, and as a result every single bit, every single smile you get feels earned. There's this really weird feeling of satisfaction when the ice is finally broken and youre kissing her off to school, in a way maybe only bros with ice queens for sisters can understand. So can I recommend this? Well fuck yeah. Its one of those rare cohabitation games thats doing nothing special but so satisfyingly tight it reminds me of the original imouto monochrome, and thats saying alot.
