Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 19 → 0.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

ストーリーの見せ方が本当にすごくて、気づいたら引き込まれて一気にプレイしてしまいました。 キャラクターの感情のぶつかり方とか、戦闘中の会話とか、画面演出とか、何度も「うわ、すげぇ……」となりました。 演出もめちゃくちゃ良いです。 ただ話を読むだけじゃなくて、ゲームとしてその場に巻き込まれていく感じがあって、どんどん先が見たくなる。 こういう作品に出会うためにインディーゲームを遊んでいるんだよな、と思いました。 創作の熱量がそのまま作品になっている感じがして、最高に良かったです。
ストーリーが面白かったです シューティングはアクセントとしては結構よかったかな クリア後に見る設定集みたいなのほしいです
まじで神ゲーです

this is a short, slightly yuri-tinged visual novel with a rail shooter minigame. it has twists and turns, to say the least. the game mechanics arguably function first and foremost as storytelling media, which is actually pretty cool imo. reina is an angel.
[h2] ほんとに本当に好きです [/h2] 4時間前後でクリア出来る疑似3Dシューティング × SF百合ノベル シューティングゲームとしても面白いですが、「ノベルパートが多め」と謳っている通り、シナリオの完成度やキャラクターの関係性の作り、およびそれらの魅せ方が巧いです。 日常パートを交えた意味深な前半部から、予想を超えて一気に畳みかけてくる怒涛の後半部まで、 通貫してキャラクターたちの描写に抜け目がなくクリアしたころには感情がぐちゃぐちゃになっていました。 百合要素が好きな人には特に刺さると思いますが、そうでなくても「敬愛を拗らせた嫉妬」や「抜け出せない依存心」、「表裏一体の依存と優しさ」「純粋な敬愛」が好きな人の感情も揺さぶると思います。 各章がキャラクターごとの視点によるオムニバス形式で進み、最後にはしっかり収束する点も綺麗でした。 BGMもサントラが出ていないのが不思議なくらい良く、演出としても巧く機能しておりストーリーの盛り上がりに貢献していました。 遊んで損することが無い、心に残る良作です。
后末日百合主题+独特的射击玩法。总共5个章节,很短,每个章节各有一个POV人物,代入感很强。多个不同POV的章节构成多线叙事方式,让人不由得期待接下来的剧情将会如何发展。 第四章的剧情展开极其致郁、令人窒息,结尾稍显宽慰,但总体主题还是比较沉重的。有点EVA的感觉,但比那个后劲更大。 是剧情顶级的好游戏,在steam上难得一见。 10/10好评!
色んな意味で重い、あと終盤の展開がわけ分からないものになっていたが、ハッピーエンドでめでたしちゃおう
It's a fun game with interesting visuals. Is not an arcade game, instead you pick one of the girls and follow the story from their perspective. Each girl has different stats, usually the next one is weaker, so the game gets harder as you progress. The story has sci-fi, horror and action elements, if you like anime of these genres you like this as well. Is not groundbreaking but is well put together.
Short and sweet game, I completed it in one 3-hours-long sitting. The story has some very nice twists I didn't see coming and the gameplay is simple and snappy. I didn't find it frustrating at all, even if I had to repeat some of the boss fights. After clearing the 5 main story chapters there isn't much else to do. The game could have used an infinite mode as an extra, similar to a certain late section of Chapter 4, but I got exactly what I wanted from the main mode, so it's fine. The connection between Chapter 4 and 5 was somewhat unexplained and left to imagination, as well as the fate of a certain character. But, overall, it was totally worth playing. The end of Chapter 4 is fairly heartwrenching, so be warned. The game has a couple of negative sides: * if you want to replay any chapter, you can't skip any cutscene. I wish there was a way to just go again through the gameplay segments * there is no way to select which part of a chapter to start from after completing it. This would be have been great for Chapter 4, which is very long and has one interesting gameplay segment I wanted to go through again, but I don't want to replay all of it just for that. * once you start a chapter, there is no way to go back to the chapter selection screen. If you go back to the main menu and select Main Mode again, the chapter you left resumes automatically from where you left it. I had a good time with it, I just wish it had some extra QoL that made repeated playthroughs smoother.
最近流行の適当にいちゃこくだけの百合とは違って、しっかり全員性愛の醜さが現れてて良かったです。
