### 4/5 — 引き継ぎできない、、？

*2026-07-12, version 3.5*

昔の端末でずっと遊ばせてもらっていたのですが、先日機種を変えてスマホの引き継ぎをしました。他のゲームのデータは全て引き継がれたのですが、このアプリだけリセットされてしまっています。どうにかして引き継げないでしょうか、、、。

### 5/5 — 信用してる

*2026-05-31, version 3.5*

この会社のアプリは、シンプルで使いやすくイラロジを長年使わせていただいてます。その流れでこのアプリもダウンロード。
容量も無駄に大きくなく、スマホが熱を発することもなく、Wi-Fi未使用時でもゆっくり遊んでいられます。
広告は短いですし、今のところ変な広告も見ていないし、必要以上の広告をみさせるとか、ブーストの課金をさせる為に解けない局面にもっていくこともありません。
誠実な会社さんだと思います。
