Cruise holds where you leave it — drag the right strip to change it, below the line for astern on a boat. Hold = power only while your thumb is down.
fire
The weapon already aims itself. On AUTO it shoots whenever a longship is in the cone, and the FIRE button is a manual override — which leaves your thumb for the water cannon.
tilt
Tip the phone to trim, and optionally to steer. Your thumb on the stick always wins, on both axes. Needs https.
hand
buttons
camera
How much the chase camera moves: the view widening as you wind it on, the swing through a carve, the kick on a hit and the drop when you land. FULL is the arcade setting. REDUCED is about half of it. OFF holds the camera still. Your device asking for less motion picks REDUCED for you.
sound
music
SOUND is all of it — engine, raid and music. MUSIC is the score on its own, so you can keep the engine and lose the music: FULL is the bed and its pulse, BED keeps the bed and drops the pulse, OFF stops it. A device asking for less motion starts on BED. Free ride has no music at any setting — there the engine is the music. On a keyboard: O for music, Shift+O for sound.
