The objective of Apple Hunt is to throw the apples into the basket in as few tries as possible.
Set Angle: Left-Click
Set Power/Throw: Left-Click again
The arrow on the map points to the basket, but you won't be able to see the basket until you throw the apple closer to it. If you end up right next to the basket, aim down at it, then let the power meter go almost all the way down before throwing. To throw an apple at full power, double-click as quickly as you can.
