Very nice, but please don't rely on keys like 'y' being on a certain position on the keyboard – on my German keyboard, for example, it's where the US's 'z' is. Other keyboard layouts are even more different.
If you can't access the physical layout of your keyboard (and using javascript, I'm not sure you can), using the arrow keys for all navigational things is really the best option.
It runs very slowly for me, but the render quality is also very good for a road engine. I don't think I've seen one that shows such an enormous draw distance before.

I suspect you have installed something like the 'HTTPS Everywhere' extension, which is doing that redirection to https for you. github.io certainly doesn't do it by itself.
