The closer the moon is to the top of the screen when you hit him, the more points you get. Look carefully to see the thin blue line near the top; it indicates the 10-point zone. As long as any part of the moon is over that blue line when hit, you will score 10 points.Each time you score a 10-point hit, you will build the double multiplier. After three consecutive long shots, the double multiplier will activate. As long as you continue to get long shots, every shot will be worth 20 points. The number of points you get from hitting the moon will scroll the screen up. At certain point values, a dotted line goal marker will appear. Pass those goal lines to earn a heart. Each heart allows one miss or a hit on a red thing without ending the game. Additionally, if you are on a double multiplier, sometimes you will pass a double goal (passing two lines with one shot), which will destroy one of the angry red things.
