### 3/5 — 追いつかない自軍のインフレ

*2025-08-05, version 1.0.36*

クッキーを増やした時代から、放置/クリッカージャンルには付き物の"転生"ギミックですが、今作は恩恵が薄いように感じます
転生を行うことで強くなった！という楽しさが欲しいのに、モンスターの進化リセットも相まってとにかくのろのろ進行。
正直2転もしたら武闘家は一時間で倒せて欲しい…なんならしない方が楽なのかも？と思います。
気長に遊ぶ人向け。

### 4/5 — nostalgic

*2024-09-08, version 1.0.36*

I remember this game being a lot different. I enjoy this version of the game, but I hope they'll bring back the old one someday as well. I loved it back then. I wish I knew what the capsules/items did or how to use them, it's never explained

### 3/5 — ゲーム楽しいが問題あり

*2024-04-04, version 1.0.36*

ゲームは楽しいけど、広告見た後の画面で左上の×ボタンを押しても反応しない。

### 2/5 — アイテムの入手条件さえ緩和すれば

*2023-11-22, version 1.0.36*

流石に広告いちいち見ないと進化素材入らないのはないと思います。
広告ブロッカー購入可能なら良い...と思いましたが240円とはいえ1日限定はあまりにもぼったくりかと
せめて1週間持たせるか、2000円程度で恒久にするか、宝箱以外に進化アイテムの入手方法(デイリークエスト設けるなど)ないとお勧めできません

### 1/5 — Just a tapping game.

*2021-11-23, version 1.0.33*

Thought this game was gonna be a way cooler build up your evil forces and take over the world type of game. Nope, just tapping

### 3/5 — Could be better

*2021-06-26, version 1.0.33*

Fun for about twenty minutes, then progression becomes very slow. The tapping sound is also ridiculously annoying. 
Game started randomly crashing; not sure if it’s my fault or an issue with the game.

### 4/5 — アイテム

*2021-03-27, version 1.0.33*

面白いがアイテムの上から3段目、右から2個目のアイテムが解放されない。

### 3/5 — これは自分が悪いんだけど

*2020-09-08, version 1.0.32*

宝箱の広告消し課金、永続かと思ったら一日だけだった。
一日で240円は高く無いかい、1日だけとかならせめて100円とかでいいだろう・・・。
ゲーム自体は今のところ結構好き。

### 5/5 — 魔王最高

*2020-08-29, version 1.0.32*

勇者に倒され続けている魔王
その魔王が主役の放置ゲーム良いですね。捕らえてお仕置き出来るのは嬉しい。捕らえられた女の子の声も聴けるなんて良いですね。

### 5/5 — おもろい、腐女向け？

*2020-08-29, version 1.0.32*

普通に楽しい。おしおきがなんつうか、加減？
わかんないけどおもろいから☆5。
