やった時間が、目に見えて増える形に変わり続けるアプリです。 ■ 積んだ時間がツリーを開ける タイマーを回した分がスキルの経験値になります。経験値が貯まるとスキルのランクが上がり、前提スキルが初級に届くと、その先のノードが解放されます。 分野もスキルも自分で作ります。「学習」でも「体づくり」でも「創作」でも、何のツリーを育てるかは自由です。最初は例として3分野・7スキルが入っています。 25分以上をまとめて計測すると経験値に20%上乗せされます。逆に、1日にタイマーで得られる経験値には上限を設けてあります。長く回せば回すだけ伸びる作りにはしていません。 ■ クエストは3種類 ・デイリー … その日のうちに片付けるもの。曜日を絞れます ・習慣 … 何度でも押せるもの。押さなくても減点はありません ・ToDo … 1回きり。達成したらしまわれます 難易度は4段階。続けた日数に応じて報酬が最大60%まで増えます。 ■ サボった日と、そこからの戻り方 対象のデイリーを落とした日は HP が減ります。全部達成した日は回復します。HP が尽きると気絶し、持っているゴールドの一部を失います。ただしレベルも解放したスキルも装備も失いません。積み上げたものは奪いません。 そして罰には必ず逃げ道を用意してあります。 ・休息曜日 … 週に2日まで指定できます。その曜日は判定そのものをしません ・ストリークフリーズ … 7日続けるごとに1個(最大3個)。差し引きマイナスの日を無傷にします ・復帰猶予 … 3日以上あいた場合、まとめて引かず最後の1日ぶんだけにします 久しぶりに開いた瞬間に全部持っていかれると、そこで終わってしまうからです。 ■ ゴールドで見た目を変える タイマーとクエストでゴールドが貯まります。武器・防具・頭・ペット・背景の5スロット、計20種類から選んで着せ替えられます。買ったものはその場で装備されます。前のものも手元に残るので、いつでも戻せます。 ■ 端末の中で完結します アカウント登録はありません。広告もありません。課金もありません。記録はすべて端末内に保存されます。 順位や実績を見たい場合だけ Game Center にサインインしてください。累計経験値・最長連続日数・計測した合計時間の3つが順位に載ります。サインインしなくても、アプリの機能はすべて使えます。 ■ 対応 iPhone / iPad
