Made some changes to the spec!

• Pong mechanics:
  • A spark bouncing between the speech bubbles, behaving as the ball.
  • NPC and player’s speech bubbles, used as the paddles. They’re moved on the vertical axis to hit the spark back and forth.
• Point system:
  • If the player or the NPC misses the spark, the other side gains a point.
    
  • If the player says the wrong thing, they lose points.
    
• Win and fail states:
  • The game ends with the player winning if they reach the end of the conversation without their score becoming zero.
  • If their score reaches zero, the conversation fails and the player begins again.
