Is this link better?
I can make it so you can use both letters and arrows move quite easily, and I'll probably do that next. As for the letters thing, most games use a and d, which is why I used it. In a 3d game, a is left and d is right, with s and w being back and forward respectively, so it just made sense to me.
But I'll absolutely add arrow key support.
