Creator here - this was much more technically difficult than it seems, because rendering pixel perfect backgrounds with scaling width is non-obvious. Hit 'Esc' and you can set some options, including changing the background pattern.

On the loading page you can click the word "Esc" to open the options menu and set the speed there. If you select "full line render" you can then set it from .25x to 10x speed and it doesn't do the character-by-character rendering.
