### 1/5 — 広告

*2026-08-22*

数日前から広告を見ても最後の最後で画面が固まるし、そもそも広告の時に上に表示されるゲージが全く進みません。
広告を見たら報酬増える〜みたいなやつは広告を見せられるだけです。
報酬として広告の画面をずっと見続けることができる権利を得られます。

### 5/5 — 広告

*2026-07-06*

広告除去を購入しているのですがたまに広告が出るのを直していただきたいです。

**Developer response:** ご購入いただいたにもかかわらず、ご不便をおかけして申し訳ありません。

調査の結果、起動直後や通信が不安定なときにストアから購入情報を一時的に確認できないことがあり、その際に広告除去が誤って「未購入」と判定されて広告が表示されてしまう場合があることが分かりました。

バージョン 1.2.15 で修正し、現在は同様の現象の報告は確認されておりません。

貴重なご指摘をありがとうございました。今後も改善を続けてまいります。

### 5/5 — めちゃおもろい

*2026-06-05*

今後のアップデートにも期待

### 3/5 — もうちょいユーザーのこと考えて

*2026-06-03*

広告カットを購入して2週間くらいやりました。

最初は強化による変化を大きく感じる事ができて楽しめましたが、段々と進みが悪くなっていきました。

バランスが悪いと感じたことを羅列します

・スーパークリティカル依存ゲー
やってればわかりますがこれが出ないと進めなくなります。なのにこれの発動確率を強化するのに膨大な資源が必要です。確率3%前後のお祈りゲーになります。

・オフライン進行の不出来さ
→ワールドが2つありますが、片方を選択しているともう片方はオフライン報酬が入りません。これがとにかく不愉快です。

・強化コストのアンバランスさ
→前述のスーパークリティカルもそうですが、ワールド2のクリティカル確率の強化コストも異常と言わざるを得ません。
ゲームの進行速度ほとんどここで決まってしまいます。

・プレステージのハードルが高い
→定期的に採掘した宝石と課金石の交換が可能になるので、安易にプレステージしにくい。
また、プレステージで変化するのは資源倍率のみで変化が少なすぎる。

考えればまだ出てきそうですが、とりあえずプレイして快適で、楽しいと思える内容に改善して欲しいです。

### 3/5 — オフライン仕様

*2026-05-24*

せめてオフラインでも鉱石を入手できるようにして欲しい。
取引がオンライン放置前提なのが惜しい。

### 5/5 — fun progression

*2026-05-15*

good simple idle fun

### 5/5 — ゲームは面白いですが、端末への負荷が課題です

*2026-05-14*

育成が楽しくてやり込める素晴らしいゲームです。ただ、以下の点が改善されればより遊びやすくなると思います。

1 発熱と電池持ちの改善： 10分ほどのプレイで端末が熱くなり、電池も急激に減ります。
2 報酬バランスの調整： オンライン報酬がオフラインの3〜4倍と高すぎるため、常にアプリを起動し続ける必要があります。

「放置」でもしっかり楽しめるよう、オフライン報酬の底上げと、アプリの軽量化をぜひお願いいたします！

**Developer response:** 発熱の問題ですが、おかげさまで先日のアップデートで大幅に改善することが出来ました。高評価やご協力大変ありがとうございます！これからも継続的に改善に努めてまいります。
２つ目についても、オフライン時にも深度が進むような計算を考えていきたいと思います。

### 5/5 — 細かいアプデが嬉しい

*2026-05-11*

痒いところに手が届くようなアップデートが多くて嬉しい。セールも定期的にお願いします！

### 5/5 — What idle is all about

*2026-04-25*

Great game, great dev.

### 5/5 — 神ゲー

*2026-04-12*

神ゲーすぎて毛根復活しました。
