How to Play Juka and the Monophonic Menace
Quick start
Choose New Game, select a language and follow Bufo's opening lesson in the Ruins. Move down-right to the first sound machine, open potions with R and select the Sleep Potion with A; when it fails, hold A to raise the Light Shield, catch the correct sound shapes in order and press R to fire them back. The real journey then begins in the Meadow.
Controls
D-pad moves. SELECT opens the Potion Mixer/Map/Journal menu, L switches targets and R opens potions; A selects/uses the highlighted potion and B exits. At a sound machine, A raises the Light Shield and B the Dark Shield, then R fires a completed captured sequence. Swimming: B dives/surfaces. START has no documented main action; save at signposts with A.
