`main loop
  do
    if title_=1 then title()

add the texture flag when you load the image.
this:

+ Code Snippet

load image "sprites/title.png",1

should be this:

+ Code Snippet

load image "sprites/title.png",1,1

edit: looking closer at your png file, you antialiased the lettering against the red which gives you softer edges. that's all well and good but the "pink" pixels between pure white and pure red and still gonna show. so, giving a heads up there incase you weren't expecting that. i whipped up a similar image with a transparent background that should look a bit better (i tried to stay close to your current font/layout but did it pretty quickly). feel free to use it if you wish (note: use the download button to retrieve the actual .png file. the view button won't get you the right one, nor will right-clicking the image itself and using "save as"):
