Wow. I wish I had even just half the talent of HTML/CSS/Javascript to pull something off of this calibre. I am really impressed, I can't wait to get my hands on this and deconstruct how they did it the best I can and play it too.
I think you should pickup openGL/webGL instead of that other stuff, if you are serious and not trolling. Because I really can't tell at this point in the thread.
I'll just remain appreciating what these developers have been able to do from a distance until I can learn the basics myself. Programming these games is only half the work, it's the art direction, storyline and mechanics that make up the other 50% of the work to make a game in any language or framework.
