Large text in the web site and in the game
The Opera web browser has been able to do this for years. Firefox can't expand the whole page yet, but it will make just the text larger or smaller. (The "text size" button on Internet Explorer is not as good, as it doesn't work with a lot of web sites. It's better to use Zoom instead.)
Zoom works for every web site, not just this one, so it would be silly to make a separate large version of this site. All you need is one of the latest browsers. If you don't have them you can easily find them on Google. They cost nothing.
Large text on the web site
The text on this site is too small for some people. I was going to make a large text version of this site, then I discovered the "zoom" option on Internet Explorer, which is a much better solution.
If you use Internet Explorer 7, just press 'Ctrl' and + or - to make the whole page larger or smaller. Or choose from the menu: Page -> Zoom.
Large text in the game
The game runs full screen at 640 x 480 pixels. If your screen is normally set to be 1280 pixels wide then the text will look this big:
If you can read that then you'll have no trouble reading the text in the game. And you can make the text faster or slower in the game by using the 'up' and 'down' arrows on your keyboard. And there are no timed puzzles, so you can take as long as you like over everything.
