Welcomed by eleven others who were brought there the same way, Remi spends his days in carefree happiness.
“Maybe I really can live here as a new version of myself.”

Twelve people with very different personalities are gathered together in the Mansion.
Remi – A book-loving second-year high school boy and the protagonist of the story. Quiet, observant, and easily swept along by others.
Saeki – CEO of a well-known start-up company. The first person to arrive at the Mansion.
Carin – A freelance web designer. Bright, considerate, and the natural mood-maker of the group.
Takuto – A self-proclaimed ordinary office worker. Always joking around and goofing off, but sharp when it counts.
Kaede – The daughter of a traditional tea ceremony family. Calm and composed, trying her best to act like the mature voice of reason.
Yuki – A 19-year-old woman with a mild, laid-back personality. Enjoys crochet and baking sweets.
Kai – A young man who works at his family’s greengrocer. A reliable big-brother type who looks after everyone.
Luca – A first-year high school boy. Serious and intelligent; he quickly becomes the person Remi can talk to most easily.
Aki – A gifted artist who mostly shuts himself in his room, drawing. Speaks very little and remains shrouded in mystery.
Erika – A third-year middle school girl. Cheerful, competitive, and bursting with energy.
Jay – A guitarist. Acts tough and foul-mouthed, but is more kind-hearted than he lets on.
Aya – A first-year university student. Quiet and distant at first glance, she keeps others at arm’s length while hiding her true interests.

15周年を迎えたフリーゲーム作品の移植版。 この作品は一つのミステリー作品であり、LTLシリーズの『入り口』となる作品でもあります。 先行配信中のスマホ版は館以降の作品や外伝が豊富に収録されているため、世界観やキャラクターにハマった人はぜひ覗いてみてください。全作クオリティ非常に高め。 一見純粋なミステリーノベルに見えますが、本質は違った場所にあります。 リアルに通用する人間・社会心理学に踏み込んだ要素が濃く、一言で説明するのがなかなか難しいです。 ストアページをよく見ると注意喚起が多い部分があります、これはある種ヒントだと思う。 特に抵抗がない方はやってみてはいかがでしょうか。 時代の流れと共に作品を知らない方も増えてきたようですが現代で遊ばれないのはあまりに勿体無いと感じる名作です。
虽然已经在手机上玩过一遍了,但还是购入了电脑版 是一款精彩绝伦的推理游戏!如果喜欢这类型的游戏请务必下载下来玩玩看 LTL系列无论哪一部都非常优秀,希望以后能继续推出更多新内容 当然也请不要忘记曾经出现过的角色,特别喜欢他们...... 总之就是购入绝对不亏,非常喜欢❤️我会一直支持的
I'd give this a 6/10. The English translation is decent. There are a few questionable translations but it's a good read for the most part. The mystery is alright, but when it's revealed how the killer took people out, it will be clear that a good chunk of the cast was taken out like chumps. The secret of how to escape the mansion felt like a deus ex machina combined with a hail mary toss. A big point in the game's favor is that the characters who get bumped off actually get some development. I wanted more intrigue. By Chapter 3, the Slice of Life sections get replaced with a setup for a revolution plotline. But that gets tossed for a mid-tier murder mystery plotline in Chapter 4. I am aware that the VN's main selling point is the murder mystery, but the revolution plotline showed promise. An alt timeline battle of wits story between the rebels and the four in charge would've been great - way better than what we got imo. A bunch of plot points end up meaning nothing for solving the mystery. [spoiler]I was sure that the death sentence thing in the House Rules would matter. Nope.[/spoiler] There's a short after story that unlocks when you complete the main story. It gives some extra backstory context but it doesn't give much more than what you already gather from the main story. Still, the after story is worth checking out, I suppose. Overall, I'd say the game is worth checking out. Get on sale.
After 6.7 hours it was a beautiful story but I didn't like one of the last characters and this is part of a series and this had very good writing, story, art, and music but I don't like how that last character made me feel after such a beautiful story.....bad taste in my mouth.....I remember the good time playing this but I don't like the sequel character so much and I liked this setting I wish they had kept the original setting going on longer and I hope they do with more adventures in the Mansion of Gluttony but after the first episode it's spoiled and the second it's really spoiled. Nevertheless great story worth it at full price. It's a very beautiful story but I don't think it really has an impact unless you are like able to commiserate with all of the characters...but maybe you can! They certainly are relatable. Anyway 9.5/10 because the last character kind of acts like a spoiled brat...No I am not sorry I am just upset about all those warm toucny feeling sensations I had just be ruined.
Firstly, just wanted to express appreciation for the English translation; I imagine it is an especially difficult challenge to translate a "fair-play" murder mystery where readers are combing over every line for clues, but it was clear, enjoyable to read through and understand, and I didn't encounter any issues or bugs with it. I'm more mixed on the content of the game itself, but overall I do recommend it. For positives, I think they did a great job of developing the characters, which is no easy feat with a large cast and short-ish runtime. While not as eccentric as something like Danganronpa, each had distinct, memorable personalities and some time to shine. I also thought they behaved in realistic ways when murders started occurring, and was engrossed in the plot. I was generally impressed with the pacing as well. Again, not easy to develop a 12-person cast and then both execute and solve a string of murders in an 8 Hour runtime, but it was enjoyable to read through from start to finish, with the exception of a slightly rushed ending. My big criticism of it is the "murder-mystery" itself. While it is enjoyable to read through, the description advertises it as a "fair-play" murder mystery that you can solve on your own. I've read my fair share of Agatha Christie and similar novels, and the best ones make you say "Wow, how did I miss that?" when the culprit is revealed. This one was an eye-roll and a "Really? Come on." It is a slippery slope mixing supernatural elements into a crime and asking the reader to solve it due to the overwhelming number of doors it opens, and it just didn't stick the landing here in my opinion. Overall though, I really did enjoy my time with Loop the Loop and would recommend it, especially to any other murder-mystery fiends out there that read every "And Then There Were None" homage under the sun. I am looking forward to reading the sequel if it is translated as well, even if I won't be as hung up on "solving" it and just sitting back and enjoying the ride.
LOOP THE LOOP The Mansion of Gluttony is a 'fine' game. It is fine. I wouldn't exactly recommend it to other people, but it's also not bad enough to deserve a 'Not Recommend', so it is sitting in this 'Mixed' limbo for me. For the majority of its runtime, the majority of the cast gets pushed to the side and ignored aside from the few core cast members, leaving the story feeling incredibly unbalanced, and if/when they eventually die there isn't much of an impact other than 'oh I guess they are gone now'. The explanation for how it went down also felt half baked, like they had a solid concept for the Mansion's rules, but couldn't execute properly on it for the murder mystery. But I wouldn't say anything about it was that bad, which is why I describe it as 'fine'. As of writing this review I haven't read [spoiler]episode 0[/spoiler] but the main story probably what you are coming for anyway if you are interested in the premise. It was a half decent, enjoyable read and if you are okay with Kinetic Novels and aren't desperately for something you can properly sink your teeth into, then maybe pick it up if its on sale? But there are better mystery Kinetic/Visual novels out there if you can find them.
