「うまうまひひーん」 かんたん操作で遊べる、言葉あつめアクションゲームです。 世界観とテーマ ここは、言葉がちからを持つふしぎな世界。 「ことば牧場」や「もじの草原」には、忘れられた言葉がボールになって、空にバラバラに飛んでいってしまいました。 そのボールを集めて、言葉をならべると、願いがかなうと言われています。 主人公と目的 主人公は、午年にウマれて名前もウマ子の、ちょっと内気な女の子。 動物や友だちを助けるのが大好きな、やさしい子です。 ある日、牧場のウマが「声」を失って鳴けなくなってしまいました。 ウマにもう一度「うまうまひひーん!」と元気に鳴いてもらうために、言葉のボールを集める旅に出ます。 ゲームの遊びかた ・右からとんでくる「文字ボール」をキャッチして、つぎの並びを完成させましょう。  「う」「ま」「う」「ま」「ひ」「ひ」「ー」「ん」 ・取りすぎるとミスになって、減点されます。 ・正しく文字をそろえるとステージクリア。つぎのレベルへ進めます。 ・道中では、とつぜん爆弾もとんできます。 ・爆弾に当たるとゲームオーバーです。 操作方法 ・画面をタップすると、キャラクターが加速して前に進みます。 ・指をはなすと、減速してうしろに下がります。
