It sounds more like just bug fixing and adding two features (saving to cloud and achievements) from the original client back when the original PC/PS version was released where as an HD remake would be almost like making a whole new game.

If you're going to advertise your website (or belongs to your friends), at least have the balls to say it's your/their website that you're making and want people to see it. It's fine and all to explore how websites work in general by making websites even with built in WYSIWYG style tools.
