Cthulhu Mythos ADV The Isle Of Ubohoth

（2024年7月3日情報を得たり気になる点が変わったこともあり書き直しました） ノベルゲームとしてはもっと完成度の高い作品はあるかと思いますが、 その点も「TRPGをしている」という感覚を高めてくれる気がします。 前作の「画面からじわじわ漂い続ける狂気」は今作では控えめですが、 「前作のキャラクターが好きな方、今作のキャラクターが気になる方」、「TRPGをプレイする感覚に触れてみたい方」には特におすすめです。 私は前作の3人とその絆が好きだったため、続投で後日譚を出していただけてとても嬉しいです。デフォルト主人公の名前もわかってばんざい！ 3人とも魅力全開で絆もより深く魅せてくれましたし、ユキツネとホタルもとても好きになりました。 主人公は立ち絵も差し替えられるくらいなので具体的にどういうキャラクターかはプレイヤーの想像にゆだねられていますが、その上で魅力が伝わるよう書かれているのがすてきです。（とはいえ限界はあるので、ある程度は主人公属性な性格のキャラクターを想像するほうが没入しやすいかと思います） 【ここから若干ネタバレあり】 エンディングがいくつあるのか、どうやってたどりつくのか ヒントと２周目以降ダイス出目操作機能があればいいなぁと思います。 ⇒7月2日、公式Xにてエンディングリストが公開されました。有難うございます！ 分岐はわかりやすい条件とわかりづらい条件があり、普通のほのぼの恋愛ADVの 思考で当たると全ED回収は難しそうです。これはクトゥルフです…。 全EDを見てこそのゲームに思えるので頑張りますが、攻略下手なので やはりヒントと出目操作機能があれば助かります…。（どういうルートに分岐するのかは ゲーム内でなんとなく想像つくのですが、どこで何の条件で分岐するかが難しく、 あるルートに分岐した瞬間「ここで？！」とびっくりしました） スチルCG、2枚解放されました。不具合でなく良かったです。疑ってすみません。 不具合かもと気になる点は下記に。 ・ボイスが一部再生されない？（公式Xのキャラクター別PVで流れている台詞で ゲーム内で再生されないものがいくつかあるような。ぜひゲーム本編で聴きたいです！） ・あるルートの最終戦闘でステータスが表示されない ・あるルートの最後のほう、ずっと同じBGMなのに（画面が何回も切り替わるからか）ブツブツ切れて最初から繰り返し流れるのが少し落ち着かないです。 ・不具合ではないですが、他の方も書いていらっしゃるようにダイスの出目６と９の見分けがつきやすいと嬉しいです。 ・上記でも書いた通り２周目以降のダイス出目操作機能があると助かります…！

Developed and published by Gotcha Gotcha Games, Cthulhu Mythos ADV The Isle Of Ubohoth delivers a story-focused horror adventure that combines visual novel storytelling with tabletop-inspired role-playing mechanics. The narrative begins on a remote island in Japan's Seto Inland Sea, where an old legend claims that anyone who successfully completes a pilgrimage across its eighty-eight temples can summon the revered monk Kukai to grant a heartfelt wish. What initially appears to be a journey rooted in folklore soon transforms into a terrifying descent into cosmic horror when the protagonist becomes entangled with an ancient curse tied to Ubohoth, a primordial entity imprisoned beneath the island. The result is a mystery filled with supernatural encounters, dangerous investigations, and difficult choices that shape the direction of the adventure. Rather than presenting a straightforward visual novel, the game introduces RPG systems that add variety to each playthrough. Players create their protagonist by answering personality-based questions, determining the character's attributes before the story begins. These statistics directly affect dialogue choices, investigations, and encounters through dice-roll mechanics that determine whether important actions succeed or fail. The inclusion of luck-based outcomes gives every major decision an added sense of suspense, making even familiar scenarios feel unpredictable. Customizing the protagonist's appearance also helps strengthen immersion, allowing players to feel more connected to the unfolding mystery as they struggle against increasingly overwhelming supernatural forces. The storytelling is clearly inspired by the works of H.P. Lovecraft, emphasizing slow-building psychological horror instead of relying on frequent scares or constant action. The island itself becomes one of the game's greatest strengths, serving as an isolated setting where every abandoned shrine, hidden pathway, and forgotten legend gradually uncovers disturbing truths. As the investigation progresses, players encounter forbidden knowledge, mysterious rituals, and unimaginable beings that reinforce the feeling that humanity is insignificant against ancient cosmic powers. The narrative maintains a steady pace, encouraging careful observation and rewarding those who enjoy unraveling layered mysteries instead of rushing through action-heavy sequences. The presentation complements the atmosphere with attractive anime-style character artwork and detailed environmental illustrations that effectively capture both the island's natural beauty and its unsettling aura. The Complete Edition expands the experience with additional content and numerous quality-of-life improvements, including new puzzles, collectible notes, Harasho's Journal, enhanced visual effects, adjustable gameplay options for success rates, and various refinements that make exploration and investigation feel more rewarding. While some background artwork incorporates AI-assisted assets, the overall visual identity remains consistent and succeeds in supporting the game's eerie tone. Its gameplay will naturally appeal more to players who appreciate narrative adventures than those looking for fast-paced horror. Reading dialogue, solving mysteries, and managing character statistics occupy much of the experience, while dice rolls can occasionally produce failures that may frustrate players hoping for greater control over outcomes. However, these mechanics also reinforce the tabletop inspiration and encourage multiple playthroughs, as different character builds and choices can lead to varied experiences. The mature themes, occasional graphic content, and emphasis on psychological horror make it a title best suited for fans of Lovecraftian fiction and investigative storytelling. Cthulhu Mythos ADV The Isle Of Ubohoth successfully distinguishes itself by blending visual novel storytelling with RPG mechanics in a way that feels engaging and meaningful. Its memorable setting, layered mystery, customizable protagonist, and atmospheric presentation create a compelling supernatural adventure that remains consistently intriguing from beginning to end. Although its deliberate pacing and text-heavy structure may not appeal to every player, those who enjoy rich narratives, investigative gameplay, and cosmic horror will discover a rewarding experience that captures the unsettling spirit of Lovecraft while introducing enough unique ideas to stand on its own.
