ヒントの説明がほしい！

一手戻るとかヒントが無料で教えてもらえるとか優しい仕様だなぁと思うのですが、上級になってくるとヒントのロジックがわからなくてなんでそこに？と思ったら意味のわからないヒントをもらってもそれで進めたくないと思ってしまいます(笑)

Response from developer

レビューいただきありがとうございます。よろしければ、詰まった箇所の画像を問い合わせメールにいただけましたら、できる範囲で回答させていただきます。

要望

クラシックのデビル〜極に関しては解説をつけるべきだと思う。
理由はデビル〜極に手を出す人は極が余裕レベルの人か中上級者のはず。
しかし解説が無い事で学習もできない(特に上級者になりかけの人)→そこから進歩が出来ないから断念となるケースが非常に多いのではなかろうかと思う。
ぜひ検討してほしい。

集中してできる

初めて見たく何個かのゲームをやってみたが、考えている最中に広告が入り集中できるアプリが少なかったが、現状では広告が入らず集中してできると思います。

Bad update

Since I downloaded version 6.3, I haven’t been able to open any games in my library. I’m a long-time user, so I’m hoping you fix this quickly. Thanks
