Really doesn't nail the atmosphere it needed to in order to make it good. Gameplay is mostly wandering around looking for collectables-- that's fine as completionist content, but there's barely anything else to do. Visuals are cheap and bad (they even reuse the same model for multiple NPCs), controls are bad, cutscenes are bad, quests are bad (mostly just "go here multiple days" or "follow this person")
If you are like me and you would like to enjoy a cozy game, but find it difficult to enjoy some of the classics of the genre like Animal Crossing or Stardew Valley due to their aggressive economizing and large amount of busywork, this game might be for you. Explore, have fun, catch bugs, and don't worry about your mortgage or the fate of a whole town.
Perfect game for the summer. Very relaxing and you get to learn about life in the Japanese countryside.
Natsu-Mon: 20th Century Summer Kid is one of those rare titles that doesn’t chase trends or try to dazzle with spectacle. Instead, it leans fully into a deeply nostalgic, emotionally grounded experience that draws you in through its gentle pacing, quiet storytelling, and an almost meditative open-world structure. Developed by TOYBOX Inc. and Millennium Kitchen—best known for Boku no Natsuyasumi—and published by Spike Chunsoft, Natsu-Mon offers a kind of digital summer vacation, the kind you might remember fondly from childhood, or perhaps never had, but always wished for. The game begins as you arrive in Yomogi Town as Satoru, a curious and imaginative ten-year-old boy whose parents run a traveling circus. With the circus setting up camp in this idyllic rural town for the month of August, Satoru is essentially free to roam. From day one, you're given the freedom to explore a sprawling countryside filled with forest trails, beaches, rivers, caves, temples, rice fields, hills, and small-town landmarks like the train station, the local shops, and the library. The open world is impressively seamless—there are no loading screens between areas, which gives the game a rare immersive quality. You can walk, swim, climb, or even ride a train to distant corners of the map, and it all feels connected and real, not just in terms of space, but time and atmosphere as well. The day-to-day gameplay is structured around a simple rhythm: you wake up, eat breakfast, participate in morning radio calisthenics, and then the day is yours. Whether you’re catching bugs, fishing, helping townspeople with little favors, managing circus performances, or just wandering and discovering hidden spots, everything you do feels purposeful even when it's mundane. This is a game about the beauty of small moments. You might spend an afternoon looking for rare beetles, or helping a local child overcome his fear of swimming. You might stumble upon a mysterious cave or decide to ride the local train just to see where it goes. It doesn’t force objectives on you, but invites you to discover your own pace and your own priorities. One of the central features is the circus itself, which acts as both a narrative anchor and a creative outlet. You’re tasked with helping organize performances, choosing which acts to include, setting up the show, and managing how it plays out. This adds a layer of structure to your otherwise freeform summer, and gives you the sense that you’re contributing to something communal and joyful. At the same time, it never becomes overwhelming or too gamey. The circus feels like just one more thread in the rich tapestry of town life, and the game wisely avoids turning it into a demanding management sim. What sets Natsu-Mon apart is how alive its world feels. The people of Yomogi Town have their own routines, their own personalities and backstories. Over the course of the month, you build relationships with them, not through dramatic quests or dialogue trees, but through everyday encounters. You might help a local café owner carry supplies, or chat with an old man who used to be a traveler. These interactions build naturally, and by the end of the game, you feel like a real part of the community. The writing is understated but emotionally effective, with warmth and subtle humor. The English translation, while not flawless, captures much of the charm and personality of the original Japanese script. Graphically, the game leans into a painterly, hand-drawn style that suits its nostalgic tone perfectly. The lighting, especially during sunrise and sunset, creates moments of real beauty. Technically, the PC version runs well for the most part, with options to toggle between 30 and 60 FPS and adjust overall visual quality. It’s not graphically intense, but the art direction carries it far. On Steam Deck and mid-range PCs, the game performs well, though there are occasional dips in busier areas like the circus grounds or dense forests. There’s room for improvement in the settings menu—options are limited, and players expecting deep configuration tools might be disappointed. Perhaps the most important aspect of Natsu-Mon is its treatment of time. The entire game takes place over a single month, and the days pass quickly. This adds a layer of bittersweet urgency—you want to see everything, talk to everyone, find every bug, and fish in every river, but you simply can't. The time limit isn’t restrictive, but it is ever-present, gently reminding you that summer, like childhood, is fleeting. You’ll reach the end of August with a full heart and a few regrets, wondering what else you might have discovered if you’d just taken a different path one morning or lingered a little longer at the beach. This mechanic—organic, invisible, yet deeply effective—elevates the experience beyond just exploration. It makes everything feel more meaningful. That said, the game isn’t for everyone. Its slow pace, minimal traditional gameplay mechanics, and lack of overarching plot may not appeal to players looking for action, challenge, or progression. Some may find it too meandering, and there’s no denying that it asks you to slow down and pay attention to the details. But for those willing to engage with it on its own terms, Natsu-Mon offers a rare kind of experience: contemplative, emotionally resonant, and filled with quiet joy. In the end, Natsu-Mon: 20th Century Summer Kid isn't just a game about a summer vacation—it's a game that feels like one. It captures that unique blend of freedom, boredom, discovery, and melancholy that defines childhood summers. It’s about wandering without purpose and still finding meaning, about forging memories not through spectacle but through presence. It’s a gentle, reflective journey that lingers long after the credits roll, and one of the most quietly profound games in recent memory. Rating: 10/10
現実の夏休みをいい意味でも悪い意味でも思い出せた作品。 ゲーム開始から色々とできることがあり、制限されたスタミナの中で一日を目いっぱい楽しみクエストをこなして解放される要素とそれに応じて増えるスタミナで更に色んな場所で個性的な島のみんなとの会話や友情を深め虫取り魚釣り!楽しい! ・・・とワクワクしながら楽しめるのも最初の2週間ほど 基本的にできることはその2週間+αで遊びつくしてしまう。アスレチック的な場所は城だけ、スタミナ限界も気にしなくてよくなったあとは毎日のラジオ体操とひたすら図鑑に載ってない虫の白丸を探す。みんなとの会話も非常に薄味で内容はほぼなく能動的に会話したいとは思えない。みんなにキャラ付けはされているがサトルとの会話というよりそのキャラの独り言を聞かされている感覚。 マルチエンディングらしいが色々とコンプリートしてもコンプした要素に優先度が設定されているらしくグッドエンディングなどは存在しない作品なので見たいエンディングのために要素をコンプリートしないようにする、というのがコンプ癖の人間には難しい仕様。しかも日中は時間を飛ばすことができないので二週目以降他もエンディングが見たくてもやることがなければただひたすらぼーっと空を眺めるくらいしかやることが無くゲーム内でヒマだなぁと思ったのは中々にシュールだった。 DLCも非常に薄味で少しのストーリーと虫と魚が追加されるのみ。・・・ただしこれのおかげでゲーム内で3日はやることが増えるので助かる。 なんだか前半はあんなに楽しかったはずなのに後半は急に気持ちが冷めて何に対しても飽きたなぁ・・なんて思う様が小学生時代の夏休みに祖母の家に行っていたことを思い出させられノスタルジックな気持ちにさせられた。そうか、これが夏休みか あと初日に両親がまともな理由も無しに子供を置いて急に消え、一か月も経った最終日付近でふらりと帰ってきて何事もなかったようにずっと食卓を一緒に囲んでいた今日子さんと純子ちゃんの席を奪ったのはストーリーが薄味な今作でも屈指の人間の邪悪ポイント。
あの「ぼく夏」シリーズの正統進化版! やりたいことをやってるだけでもOKのゲーム性は変わらずで、とても楽しめました。 なつもん!2を切に望みます!
Gathering simulator -50.00% Plot simulator -50.00% Talking simulator -50.00% Total -150% (FFF)
この手のゲームがもっと増えてほしいと思いますね。 最近、ぼくなつとかを実況や解説してる人も多いし、だしたらいけると思うんだよね。
My best summer vacation
Great game!
