一筆書きで、47都道府県を描け。 「わたしの日本地図」は、記憶だけを頼りに都道府県の輪郭を一筆で描く、新感覚のお絵かき評価ゲームです。描いた形は実際の県境と照合され、県ごとに異なる評価軸でスコア化されます。 ■ 形がそのまま「県の運命」になる ・能登半島が短い → 金沢金箔・海の幸スコアが激減 ・下北半島を描き忘れる → マグロに逃げられる ・土佐湾の弓なりが甘い → カツオが不漁に 名産・地理にちなんだ評価軸が、あなたの手の震えを容赦なく採点します。 ■ 3段階のガイドモード ・激甘:なぞりガイドで地図を覚える ・ノーマル:隣県のうっすらシルエットだけ ・ハード:ガイドなし、記憶のみで挑戦 ■ 手描きの日本地図が完成していく 遊ぶほどに、自分の描いた(少し歪んだ)形で日本地図が埋まっていきます。47県コンプリートは最高のスクリーンショット映え。 ■ レーダーチャート・称号・共有カード 軸別スコアをレーダーで可視化。「地図帳の妖精」「半島どこ置いてきた」など、低スコアでも笑える称号が待っています。結果はSNSでシェア。 完全オフラインで遊べます。地図データは国土数値情報(国土交通省)由来、統計値は e-Stat 等を参照した推定・目安です。 ※アプリ内課金「全国制覇パック」で全47県の開放・広告除去・称号図鑑の全解放ができます。
