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): 0.57/day in the week to Aug 27 → 0.14/day in the week after.
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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

射击百合,剧情非常刀,到最终章之前几乎透不过气,虽然是小制作,里面的演出小巧思做的还挺有意思的,最终章也足够能调动情绪
独特な面白さがある。キャラクターは良かったけど、ストーリーはちょっとわかりにくかったかな。
素晴らしい百合シューでした!市タリオに引き込まれてあっという間にクリアまで駆け抜けちゃった、勿体ない。

横スクロールでも見下ろし視点でもない3人称視点の新しいシューティングゲーム。弾幕の奥行きが把握しづらい欠点はあるけど、bgmよくて、難解だけどテンポよく進むストーリーは考察の余地があって楽しい。
ゲーム部分が単調で、避けているのかどうかもはっきりとしない感じのシューティングとなっておりやや残念。 しかしストーリーは面白く、演出やドット絵のクオリティなどビジュアルも非常に良かった。 ゲーム付きのノベルゲーと考えたほうがいいかもしれない。3DSTGの画面ならではの没入感があり読み物としてかなり斬新な体験だった。
I didn't quite grasp the plot 100%, but it was still really good. 7/10
한국어로는 없지만 재미있게 즐길 수 있었습니다. 소소한 이야기도 재미있고 캐릭터가 너무 빨리 움직여서 이 속도를 조절하면 재미있을 것 같은데 슈팅도 독특한 재미가 있었습니다. 스토리 모드 외에 챌린지 모드 같은 것도 추가 되면 즐거울 것 같습니다.
솔직히 슈팅 파트가 좀 지루한 편입니다. 다만 스토리 전개에서 드문드문 좋은 연출이 있고 나름의 흡입력도 있어서 이런 괴수물이 취향에 맞다면 세일가로 사서 해보시고 그렇지 않다면 구매하지 않는 걸 추천합니다.
