THE STORY
Kota was supposed to see the Shiratori sisters, his childhood friends, for the first time in six years, but fate had other plans. When he woke up...
He find he'd become a hamster.
The three sisters are now his owners! There's Himari, the kind and reliable eldest one; Futaba, the straight-laced middle one who's obsessed with health; and Miyu, the youngest one who's a sassy.
Kota, or rather "Hamta," his new name as a pet, was as confused by the situation as he was pleased with all the pampering.
However, he noticed something. The sisters didn't seem to get along as well as they used to.
What happened during the past six years?
You'll need to use your tiny paws and big heart as well as you can to uncover the truth and help bring them back together!

The protagonist. Right as he came back to his hometown and saw Futaba for the first time in six years, he got into a traffic incident and somehow got reincarnated into the Shiratori sisters' pet hamster.

Reviews
Максимально приятный актёрский состав(для некоторых, все старше 18 лет), включая ГГ(хомяка). Надеюсь что будет поддержка русской локализации(не машинной). Ламповое кинцо в которое хочется играть и смотреть за развитием сюжета.
HALT! If you think this will be like 5 Hearts Under One Roof go no further cause its not! This is more of a story game than dating..i mean you are a hamster so the best you're getting is to see them in swimsuits and lots of cleavage shots cause they gotta bend down to see you. its a quirky little FMV game with agonizingly long pausing between all dialogue. You go through 3 routes, each pertaining to a different sister. I've done the eldest sister's route which is basically a cosplayer route and it was an interesting? story? A lot of it was just revealing the story behind her life They give you a little hamster button you can click on to do one of 4 different types of moods ( supportive, kinda sad, love and look at me energy) a sound effect plays and some words appear on screen. It does nothing for you but fills the time between each long pause and shot of a girl staring into a camera at hamster level. Each section of a particular sister's route can have a bad end so you have to go back and choose the correct choices I'll go back and finish the of sister's routes at some point but for now I'm good. I still recommend cause its a nice little story
游戏不合格,玩了两天才打完,昏昏欲睡。 首先从锁国区来说,官方说好了中国区会售卖CDK,结果游戏发售后官方直接消失,逼迫想玩的玩家开小号转到外区去高价购买,这种发行团队的做法简直差到离谱。 游戏部分,采用GAL做法,可以查看过去的对白等,用户体验度不足,跳过放在菜单里,故事线的每个节点是一段剧情,无法从这段剧情中间某个位置去选择,且无任何成就。 游戏三个女主角,颜值一般,主打一些擦边,剧情比较简单,帮三个姐妹解决每个人内心的秘密和问题,剧情节奏缓慢至极,从来没见过这么慢的。男主角没有声音,这是日系游戏的一贯做法,增加代入感,这方面到无所谓,而且本来仓鼠也发不出什么声音。 游戏拍摄清晰度不错,但貌似帧率或码率不足,导致镜头移动时模糊。 总之,剧情简单、有擦边没那么厉害、游戏性不足、锁国区等各种问题严重。这个产品只适合想看看擦边的玩家,而且建议打三折时候再入。 This game is subpar. It took me two full days to finish, and I felt drowsy the whole time playing it. First off, the region lock issue: the publisher promised CD keys would be available for the Chinese region, yet they went completely silent right after launch. Players who wanted to experience the game were forced to create alternate accounts, switch to foreign regions, and pay exorbitant prices to buy it. The distribution team’s handling of this matter is absolutely appalling. As for gameplay, it adopts typical visual novel mechanics with a backlog feature to review past dialogue, yet the overall user experience leaves much to be desired. The skip function is buried deep in the menu. Every story checkpoint is a self-contained cutscene segment; players cannot jump to a specific mid-point within any scene, and there are zero achievements to unlock. There are three female leads with mediocre character designs, and the game relies heavily on mild suggestive fan service. The plot is extremely simplistic, revolving around helping three sisters resolve their personal traumas and inner struggles, but the pacing is unbearably slow—slower than any game I’ve ever played. The male protagonist has no voice acting, a common trope in Japanese titles meant to boost player immersion, which I don’t mind much anyway; besides, the protagonist is a hamster, which wouldn’t make vocal sounds naturally. The static image resolution is decent, but insufficient frame rate or bitrate causes noticeable blurring whenever the camera pans. All in all, the game suffers from a litany of severe flaws: shallow storytelling, tame suggestive content, lackluster gameplay, and unfair Chinese region locking. This product only appeals to players chasing mild risqué visuals, and I’d recommend waiting for a 70% discount before purchasing it. このゲームは期待外れで、クリアするのに丸二日かかった上、プレイ中ずっと眠気に襲われました。 まず地域ロックの問題から話すと、運営側は中国向け CD キーを販売すると約束していたのに、ゲーム発売後に音信不通になりました。プレイしたいユーザーは仕方なくサブアカウントを作成して海外リージョンに切り替え、高額で購入するしかない状況に追い込まれています。このパブリッシャーの対応は最悪としか言いようがありません。 ゲーム内容に関しては、過去の台詞を遡れるギャルゲー特有の仕様を採用しているものの、ユーザービリティが低いです。スキップ機能がメニューの奥に隠れている上、ストーリーの各節は一続きのシナリオ単位になっており、シナリオ途中の任意の箇所から再生することはできません。実績システムも一切実装されていません。 ヒロインは三人いますが、キャラクターデザインは普通で、軽度な際どい演出を売りにしています。ストーリー構成は単純で、三人の姉妹それぞれの内面の悩みや秘密を解決するという内容なのですが、テンポが極端に遅く、これほど進行が緩慢な作品は初めてです。主人公にボイスが無いのは、没入感を高めるための日系ゲーム定番の手法なので特に気になりません。そもそも主人公がハムスターなので声が出ないのも自然です。 静止画の解像度は悪くないのですが、フレームレートかビットレートが不足しているため、カメラが動くシーンで画像がぼやけてしまいます。 総括すると、ストーリーが薄い、際どい演出も控えめ、ゲーム性に欠ける、中国地域ロックといった重大な欠点が多数存在します。この作品は軽いエロ演出を見たい人以外にはおすすめできず、三割引になるまで購入を待った方が良いです。
Never left a review, but this game should be banned from steam. Do not buy or support this. There is an underage character story path and that should not be in any FMV game. Actually sad this was allowed on steam. Thought it was going to be a meme/laugh game, but disgusting instead. No one should support this at all
My initial thought was that they didn't quite know if they were making a fanservice game or a game with an actual story, and in the end result, both aspects were kind of half-hearted. But then I reached the last third of the game, and realized the biggest problem with the game was actually pacing. Because the story does get actually good, even really good, towards the end (Futaba's route, and the [spoiler]alternate timeline [/spoiler]), but that was after such a long wait. The first third was just ridiculous fluff, the second third focused more on the story but didn't really get anywhere, until the last third saved it. But even at the end, in [spoiler]the alternate timeline[/spoiler] where the story peaked, pacing failed in a reverse way; when things got really good, they were also rushed, almost like fast forwarded. Another thing that helped to save the game was Miyu's acting, of all the sisters it was like her actress was the only one who managed to really act their role seriously, and seriously well. Futaba's was OK, but Himari's actress was clearly not feeling it. In general, Futaba's route, [spoiler]the alternate timeline[/spoiler], and Miyu were enough to make it a recommended. On technical side, video is a bit overfiltered (some kind of denoise+sharpen combo with too aggressive parameters), but you get used to it. The timeline doesn't show dialogue branches, which is a shame and makes it impossible to track if you've watched all. Audio is generally fine, and music direction is spot on. And sadly no achievements, I hope they will add them later. Full playtime is around 6-7 hours.
まだ序盤ですが、とにかく画質が凄く綺麗で、実写ならではの臨場感に一気に引き込まれました。登場する3人のヒロインがみんな美人で、ハムスター視点で超至近距離で一緒に過ごせるという設定がいい意味でおバカですでに面白い! ヒロインに囲まれてお世話されるドキドキ感が堪りません!!!
感動的なストーリー及び解像度が高い映像。特に出演者のファンの方に勧めます。
ハムスター目線でヒロインが見つめてくる動画シーンがよかった。 とても動画もキレイで、良いゲーム。
[h3] 俺の名前は公太。目が覚めるとハムスターになっていた…! [/h3] 細かい分岐はあるが最終的には1ルート、クリアは7時間程。 ハムスターとして転生した主人公が、すれ違う三姉妹を助けるべく奮闘する。 「ご褒美4K映像」も1周で全回収出来るのが良い。 ツッコミどころも多く配信でも楽しめた(肌色の多さはちょっと心配) 個人的には二葉推し。 国産FMVとしてとても気になっていたので、リアルイベントにも参加。 「ハム太のおうち」が展示されたりしていた。
主人公がハムスターになっちゃったというアニメみたいな設定が、とても面白い世界観だと感じました。 また3人ともとても可愛いです。
