落書きで動物や植物を創造して命を紡ぐ星の運営を創造神の目線で楽しむゲームです。 他の星の神(他のプレイヤー)とも交流して、あなたの星を優雅に彩ります。 但し、爽快なバトル・壮大なストーリーはございません。 大変ごめんなさい。謹んでお詫びするね。 その様な物をお求めであれば他のゲームで満たしつつ、当ゲームを楽しんで頂ければ幸いにございます。 このゲームでは動物や植物をデザイン出来ます。 牛さんが好きであれば色とりどりの牛さんを。 ヤカンが好きなら色んな形のヤカンを描いて好きな様にして頂ければ良いのです。 他のプレイヤーと競う「コンテスト」を用意させて頂きましたが、大した物ではありません。 ご自身で目標を設定し、コツコツ遊ぶゲームとなっております。
