I have another suggestion:
The "Extra Life" setting should have options that allow players to earn more than just one extra life throughout one game. Basically, along with the four options this setting has now ("None", "10000", "15000", and "20000"), there should be new options like:
• "10000, 20000"
• "15000, 30000"
• "20000, 40000"
• "Every 10000"
• "Every 15000"
• "Every 20000"
With this, players would have the option to earn zero, one, two, or infinite bonus lives throughout a game.
