先日のエントリのとおり、Miyakoを使って、Tetrisを作ってみた。
ずいぶん時間がかかった。
Miyakoはあんまリアルタイムゲーム向きのライブラリじゃないのかな？
動きがぎくしゃく＆キー入力が微妙。
これをもう少し遊べるように改造するのはありかもしれないけど、とりあえず、「できた！」ってことで、終わりにしておこうかな。
ちなみに所要時間は、４日ぐらいかな。
スコアをつける、落下スピードを変える（早くなる）、ブロック消すときのイフェクト、次のブロックを表示、などの改善が考えられそう。
というか、こういうのを改善しないと、ゲームとしてはおもしろくないですね。
ソースは、以下に貼り付けておきます。

だけは買っていたゲームライブラリのMiyakoのインストールを試みる。
