The following review is based off my personal experience with playing this Game/Visual Novel... I try to be as brutally honest and detailed as I can, and these are my own opinions and thoughts, from one or more play throughs... The version this review is based on is v9.20...
This is an interesting and sometime hilarious visual novel/game... Too bad it is pretty much focused on the over used Family Sex stuff...
The visuals are all 2D hand drawn for both the characters and backdrops... A few of the characters have over the top sized breasts for their body frames, but this whole VN/Game is pretty much over the top and appears to work towards being silly and humorous, even visually... During some erotic scenes, the protagonists penis is a disembodied one, which for me is a turn off... Throws off the immersion... The audio is very good...
The script is pretty spot on, as I rarely ran into any spelling/grammar errors... The plot revolves around a male protagonist musician who is stuck at home with his mother and 3 sisters during a heavy snow fall, which makes it impossible to leave the house for a while... His family pretty much treats him like dirt, and since he is a pervert at heart, he decides to get revenge... He invents and uses a special metronome that hypnotizes his whole family... He then slowly, over several days, corrupts his family into lots of various erotic encounters... His overall goal being to make his family members into sex slaves... He does eventually get caught, but I'll not spoil it much more beyond that...
There are a lot of decisions to be made, and sadly this game uses a lot of player punishment bad endings if the right choices are not made... There are hidden points for each character that the protagonist interacts with, and the more correct choices the protagonist makes, the more content becomes available, while avoiding bad endings... So, the down side to all this, is that unless you plan to use a lot of save game slots, it's almost better if you use a walkthrough to experience as much content as possible... Otherwise, expect to be saving and loading game over and over again... Because you have to be really clever and think about the choices you make... I tried it a couple times without the walkthrough, and got pretty far, but it took a heck of a lot of wasted time to do it...
There are multiple endings, one ending for each female character, and once all those have been achieved, a harem ending opens up... My advice is to save the game, once you get to the point where you have to select a single girl to completely enslave... So you can go back and see all the different endings, which will then open up the harem ending (the listed True Ending)... The choice for not enslaving anyone is a bad ending, obviously...
Overall, even though the main fetish of this VN/game is Family Sex, it was still a very fun and challenging game to go through... There are moments of silliness as well as humor, but some of the choices presented really do require some clever thinking, without a walkthrough... You can't just be a total pervert with all the choices, especially with certain characters... And how the story is told is pretty darn good...
I enjoyed trying to actually figure it out on my own, but it just took a very long time, with hitting bad endings now and then, to get through it... And most walkthroughs do not include all choices in the last couple game days... So you're gonna have to figure out something on your own, anyways... The harem ending, although shorter then the single woman endings, was so completely over the top, silly, and hilarious, it had me laughing out loud several times... I don't want to give it away, so I'll not go into details...
I'm very surprised this VN/game is still showing in development, because it feels very much completed... I played it once before back in Oct 2017, and it has definitely improved since then... It's a fun and crazy VN/game, not the best, but still pretty good... Will I revisit it? Only if it actually ends up getting more content worthy of a replay, but as it stands right now, it feels done, so not sure there would be a reason to replay it... Only time will tell...
