Nice job! This is really polished and you clearly worked a lot on it!<p>A couple of quick comments on it, after playing it for 15 minutes.<p>- I didn't realize until I had been playing about 5 minutes that the box at the top needed to match the arrow at the time that the arrow boxes went in to it. When I started out, I was trying to change as soon as I saw the new directions.<p>- Nice job on the animations. I think they're just right, and you really did a great job on using the right combination of CSS and JS (imho).<p>- As a guy with a left handed friend, and working on a cramped Macbook Air keyboard it would be really nice to have WASD support.<p>Again though, awesome job!
