*2025-09-15, version 1.0.7*

とても楽しいゲームだがジャイロ機能が少し低い

### 3/5 — 悲しい…

*2025-08-16, version 1.0.7*

アプリ自体は単純で楽しいです。
ですがたまに起こるバグ？なのか初期化が辛い。
今年の元旦に初期まりもさんと突然のさような。そこから250日ぐらい育てていましたが、今朝アップデートしたら最初からになってしまいました…。愛着が湧いていたので、悲しい…。
皆様お気をつけて…。

広告多いけど面白いです

### 4/5 — まりも可愛い

*2025-06-01, version 1.0.6*

まりも可愛いんですが、名前を付けたいです。
あと、掃除などのコマンドが小さくて見づらいので、コマンドを少し大きくしてくださると助かります
また引き継ぎ機能が欲しいです。

### 5/5 — 愛着湧いてます。

名前付けれるようにして頂けたら凄く嬉しいです。
