About

Monster Girls Onsen is an 18+ anime visual novel with light management elements, set in a mystical Japanese hot spring you unexpectedly inherit.

By day, you run the onsen, serve guests, and expand its facilities.

To claim your place as the rightful master of the onsen, you must earn their trust… and satisfy their desires.

As the story unfolds, expect emotional confessions, steamy encounters, and unforgettable nights that unveil the secrets of the spirits — and the hot spring itself.

absolute garbage. Stupid boring game mechanics. An unnecessary number of houses. And most importantly: incredibly dull and hacky sex scenes. Three animations for the whole game. But there are tons of primitive and meaningless dialogues.
As a girl who appreciates beautiful art, I adored this. It's a very light and relaxing onsen experience. Don't expect deep gameplay—just sit back and enjoy the stunning artwork of these charming ladies. Short, sweet, and visually delightful.
说是魔物娘温泉,但实际上是日本各种神怪温泉 AI画的还行,但机翻散装汉化 白天的模拟经营环节说实话没啥必要,根本不会失败,纯是为了水时长
Well. You can complete it in 40 minutes and the artwork is clearly AI generated. But it's decent enough. Even if buying this sort of game encourages Skynet.
相変わらずゲームは虚無だしバグり散らかすがサンプル動画を見ての通りLive2D部分はかなり進化している 絵が合うならシコれると思うがそうでなければ [h1]果て無き虚無[/h1] [h1]死刑囚がやる刑務作業[/h1] [h1]僧侶がやる「悟り」を開くための修行[/h1]
セールでDLC入り買ったけど、かなりエロい ゲームは新しく建てた建物だけを掃除するのがポイント、お金がたくさん入るから。 掃除は連打しないと意味がないので注意、しばらく気づかなかった 「掃除はマークが消えるまで連打」これ重要、ってもうギャラリーしか見ないけど
идея не плоха но реализация так себе, за такую цену во всяком случае
so boring..i almost fall a sleep
Nesse jogo você é um homem que herda um Onsen. Durante o dia você atende os clientes e a noite você se encontra com espíritos de mulheres. História = OK. Cuidar do Onsen = Divertido. Tempo de jogo = Curto demais. Cenas +18 = Boas. Para você ter uma ideia comecei a jogar 22:20 e terminei as 23:30, lendo todos os diálogos e assistindo as cenas com calma, então você pode terminar em 25min se rushar tudo. Fiquei mais tempo no jogo só para pegar as cartinhas para vender. Pra mim foi divertido então valeu a pena, mesmo achando extremamente curto.
[b]Summary[/b] Ultra fast onsen management game that features quick, easy gameplay & beautiful youkai Heroines awaiting your hot rods. The gameplay is rather easy, just assign the customers to the requested location, clean 'em up, and before turning in for the night, deepen your relationship with the Heroines. Story is pretty straightforward, nothing fanciful ergo no need to wreck your head. Just dive in and enjoy managing the onsen~ [b]Scoring[/b] Average, 5 out of 10 [b]Verdict[/b] Recommended for players looking for relaxing management, and those that enjoys youkai Heroines. [b]Positive Highlights[/b] ☑️ Steam Achievements ☑️ Super cute chibis ☑️ Only H SFX [b]Minor Pet-peeves[/b] ❌ No Cloud saves ❌ Gameplay can be rather repetitive [b]How many shots[/b]: Minimal (1 ~ 3) [b]Best Heroine[/b]: Yukino
