### 3/5 — 面白かったけど……

*2026-06-20*

フリーズし過ぎ。
最近のOSに対してのデバッグ作業を絶対にやってませんよね？
セールで安く購入したから許せるものの……。

### 1/5 — 最高につまらない&イライラする。他レビュー最低評価ばかりwww

*2024-03-06*

・やり込み要素が少ない 　（ほぼレベルアップ作業） ・メニュー項目が見ずらい 　（異常に項目が多い&日本語がおかしい） ・戦闘が終わると全回復、状態異常回復になる超人仕様。 ・アイテム強化がリング作成のみ？？？ 　そのリング作成は1個ずつでしか選べないww めんどくさい ・スキル習得方法に難がある 　習得が難しいので結果的にスキルが少なくなる。 　単純なレベルアップではスキルは増えません、ステータスだけ上がる。 　レベルアップだけして、全体攻撃装備付けて、ひたすら殴る、回復するでクリア出来る。 ・ダンジョンにワープ機能無いw ・課金ショップのアイテム少ない（必要最低限ww） ・ある意味悪い所→スキル習得アイテムが道端に落ちてるので宝箱無視出来ない 良いところはグラフィックぐらいですかね。。 新人が作ったのか、個人が作ったのか、外国人が作ったのか、そういったレベル。

### 5/5 — 久々にヒット作！

*2022-06-12*

最近のケムコ作品はストーリーがいまいち腑に落ちなかったり、中途半端な伏線回収でモヤっとしたりするのが多かったけど、これは久々の良作でした！

戦闘バランスも良かったし、ロールシステムもちょっと面倒だけど、それがまたレベリングし過ぎの抑制にもなってて良かった(^^)

### 2/5 — Mr

*2021-02-08*

I don’t understand why so endlessly long conversations and boring  at same time.Make short and interesting and relevant to the story..Please,pretty please.Thanks

### 4/5 — Would give it 5 stars but postgame is broken

*2020-12-16*

After beating the main storyline and going to the postgame you cease to gain money, role points or experience after battle.

### 5/5 — 安定感

*2020-09-23*

*2020-07-30*

一部ユーザーも書いてると思うけど起動時〜1~30分位スマホ本体が熱を帯びます。早急に対応お願いします。作品自体はとても面白いです。今後も開発お願いします
