+Reflect
+=======
+Reflect is based on a browser game I played maybe 10 years ago on its creator's
+homepage. If you recognize the game, please contact me.
+
+Your aim is to protect cities from missiles using a paddle.
+
+Controls
+--------
+Mouse to move. Click mouse button to explode missiles you've reflected.
+
+License
