--load text colors
red = Color.new(255, 0, 0)
blue = Color.new(0, 0, 255)
green = Color.new(0, 255, 0)
black = Color.new(0, 0, 0)
white = Color.new(255, 255, 255)

--Startup
intro = Sound.load("Data/Sounds/intro.wav")
luaplayer = Image.load("Data/images/lua.png")
intro:play()
screen:blit(0, 0,  luaplayer)
screen.flip(120)
screen.waitVblankStart(120)

-- Move Player

function move()
local limit = -11 -- adjust the count limit as needed
local pad = Controls.read()

if (pad ~= oldpad) or (countpads > limit) then

if pad:right() then
playerPos = playerPos + 1
if playerPos > 13 then playerPos = 13 end
screen.waitVblankStart(2)
end

if pad:left() then
playerPos = playerPos - 1
if playerPos < 0 then playerPos = 0 end
screen.waitVblankStart(2)
end

if pad:up() then
playerPos = playerPos - 1
if playerPos < 1 then playerPos = 1 end
end

if pad == oldpad then
countpads = limit - 1 -- for repeatedly advanced
else
countpads = 0 -- for the first pressed
end
oldpad = pad
else -- do nothing for a moment
countpads = countpads + 1
screen.waitVblankStart(5)
screen.waitVblankStart(4)
screen.waitVblankStart(1)
end

end

player = Image.load "player.png"
playerPos = 1
countpads = 0

while true do

if pad:analogX() < -30 then
x = x - speed
end

if pad:analogX() > 30 then
x = x + speed
end

if pad:analogY() < -30 then
y = y - speed
end

if pad:analogY() > 30 then
y = y + speed
end

  if pad:left() then
      x = x - 3
  end

  if pad:right() then
      x = x + 3

What are the sound limitations in lua?..

I've been trying to make some background music, but what should it be in?

I've got various wavs playing on events but they fail to play when I try to start them at the main menu. I just want some background music.

Cheers.

They can only be wavs.

Well in that case, there is something wrong as the background audio I have wont play and it's a wav.
