PerfectTimingChallenge

◆30秒ぴったりでストップウォッチを止めるだけのシンプルなゲーム◆ 目標時間を設定したら、Startボタンで開始。30秒経ったと思ったらStopを押して、結果を見てみよう！というゲームです。 本当にそれだけです。暇つぶしにぴったり！ ただ、誤差0.00秒になるとちょっとメッセージが変わります。せっかくなのでそこを目指してみてください。 大学のFlutterの授業で作成し、せっかくならAppStoreに上げてみようと作りました。 たくさん遊んでいただけたら嬉しいです。 メッセージはぜひ、AppStoreの「アプリサポート」からお寄せください！ ※右上の電球ボタンから遊び方を確認できます。 ※本アプリにはGoogleが提供するAdmobを使用しバナー広告を表示しております。 ※端末本体の文字サイズ設定によっては、画面がうまく表示されないことがあります。
