missile_command_attiny85_3aliens_max.ino

/*
 * Missile command ATTINY85
 * just a minimalistic game console with:
 * an Attiny85
 * a 5 button keyboard from keyes : ref : Keyer-AD-key - KB45037
 * a 8x7 led segment max7219
 * a buzzer (optional), just for fun and because I had one pin left on the Attiny
 * 
 * How to play
 * turn on the console
 * for 2 seconds , it displays the high score
 * 
 * the game begins straight
 * SW1 : go left
 * SW2 and SW3 : go center
 * SW4 : go right
 * SW5 : shoot
 * 
 * 1 to 3 aliens are going from top to bottom
 * if it reaches the bottom , you lose 1 shield (4 shields at the beginning)
 * the shields are represented by 4 dashes at the bottom, if you lose the 4 shields, 
 * you die when the next alien reaches the bottom 
 * 
 * aliens speed is increasing during the game and when you reach some levels, 2 to 3 aliens are going down.
 * 
 * when you lose, the score is displayed for 2 seconds and then switches back and forth 
 * to the high score.
 * The high score is saved to the eeprom
 * 
 * 
 * To play again you need to push a button for a few seconds.
 *
