-### 前提・実現したいこと
+### ゲーム概要
-小林　郁夫・佐々木　晃共著の「Pythonによるプログラミング」ｐ160の練習問題8.2に取り組んでいます。pythonでブロック崩しゲームを作成しようとしています。しかし、ゲームがスタートしません。自分でも挑戦してみましたが、上手くいきません。ご教授願います。
-### 発生している問題・エラーメッセージ
+・spaceキー押下でゲーム開始
-　「Press 'SPACE' to start」も表示されず、spaceキーを押しても反応しない。
+・ゲーム開始まで「Press 'SPACE' to start」とscoreを表示
+・ランダムで矢が上から降る。その矢がパドルに当たるとゲームオーバー
+・ブロックにはbc（破壊するためにボールを当てる回数）を設定
+・ブロックにボールが当たるとスコアが加算
+・ブロックの上下左右にボールが当たる。
+・パドルにはMULTI_BALL_COUNTという定数で定めた回数ごとに一個ボールを発生させる。ボールの数がBALL_MAX_NUMに達している場合には発生しない。
-　エラーメッセージなし
+・最後のボールが底につくとゲームオーバー
+・パドルはボールが一回当たるごとに色が変化。
+・全ブロックの破壊でClear!と表示
