That's . . . bizarre. The tutorial does have the player ship in it, but just as a slide-image. The "background" is supposed to be there too. Because it is a slide it doesn't have any enemies in it, it isn't an actual tutorial level. Calling it a "tutorial" is a bit misleading because 'tis just more like "instructions" since all it has are still-images. What's happening with the settings makes no sense though . . .
Maybe this game is too powerful for your device? Although I doubt it. Does this problem exist with the exe or the browser-version?
