### 5/5 — 업데이트

*2025-09-22*

업데이트 또 언제 예정입니까?

**Developer response:** 리뷰 감사합니다! 업데이트가 늦어져서 죄송합니다. 마왕의 탑을 더 즐길 수 있도록 새로운 콘텐츠와 개선을 준비하고 있으니, 조금만 더 기다려 주세요. 앞으로도 잘 부탁드립니다!

### 4/5 — 爽快感はありませんが

*2025-05-21, version 2.9.3*

コツコツ育てる方には
面白いと思います

### 5/5 — バグとか→対応早

*2025-05-02, version 2.8.2*

機種: iPhone 13 Pro Max
あまりユーザー多くない機種かもしれませんが、UI日本語、転生の表示で”説明最後の方の、”生産ボーナス”と”次回転生で獲得できる魂ポイント”が重なるようになりました、
それほど気になる訳でもないですが。
それとアプデ後に何故か魂ショップLvが2項目何故かLv1ずつ下がりました、残念です⤵︎
そう言いながらも、app開いては塔を眺めて遊んでプレイしているので楽しませてもらってます。

英語候補:
Basic Tent そのままok思いますがplain shelterとか
骨小屋bone hutとかskeletal cabin
ゴブリンはTreasure hutとかgoblin’s hoard house
Mystic Barrier Tower
そして考えるきっかけとなったクリスタル装飾の輝く城、日本語だと気にならないですが英語的にはCrystal Palaceとかcastleくらいのシンプルな方が好まれるかも？と思いました、分かりませんが1コメント程度に。

追記
転生の表示よくなりました
魂ショップは見間違いだったかもしれないです、気にされていたら申し訳ありません。GW中にポチポチ眺めながら楽しませてもらいます

### 5/5 — 興味深い

*2025-04-30, version 2.8.1*

転生した時の次回ボーナスって何が付いてくるんですか？

返信ありがとうございます👍
暇な時間にちょうど良いので遊ばせていただいてます。

休憩所の種類を増やしてみるのもありかと思います。
収益大幅アップの効果の強化・延長、全体キャラのレベルアップコスト割引など、クリスタル装飾の輝く住居みたいに尖ったものがあっても面白いかと

### 5/5 — 無課金

*2025-04-27, version 2.8.0*

無課金でも全然楽しめるw

### 3/5 — 浅い

*2025-04-27, version 2.7.0*

よくある放置ゲー。
だけど浅すぎてすぐやる事なくなるよ。
実績はステアップとかないホントただの実績なのは笑わせてもらった

### 5/5 — すばら

*2025-03-05, version 1.3.6*

一括レベルしたいと思ったらアプデきてて神

### 3/5 — 一括レベルアップ機能が欲しい

*2025-03-04, version 1.3.5*

10区切り、50区切り、MAXとかある程度の区切りことのレベルアップ機能があるももっと楽しめると思います。
現状1ずつのレベルアップしかないので、転生後とか長時間放置した後のレベル上げが辛いです。
気づいていないだけで、すでに実装済みであれば申し訳ないです。

### 1/5 — このゲーム

*2025-02-17, version 1.2.2*

何がおもしろいのかがわからない。
時間の無駄と感じたし、時間潰しにもならない。
