DEVICE VOLUME

This slider has the same effect as the volume buttons on an iPhone, but for iPod Touch's that don't have those buttons, this is how you control the device's master volume.

MUSIC

This switch toggles the game's music on/off, and the slider sets the volume of the music.

SOUND FX

This switch toggles the game's sound effects on/off, and the slider controls the volume of the sound effects.

OFFSET RETICLE

By default this is ON. It applies to the Shootout levels where the targeting reticle is displayed. When you tap the screen to shoot, the reticle will be placed just above where you tapped instead of directly under it. This way you can see what you're shooting at without your finger obscuring it. Turning this off will make the bullets shoot from the exact point that you tap.

VIBRATION

For iPhones only, this turns the vibration on/off in the game. Normally the phone will vibrate if Billy gets hurt.

SHOW HELP TEXT

At the beginning of each level a short line of help text is displayed telling you what to do to play it.
