I'm all for spreading the word on this amazing game.
As far as things that might be missing from your article... the game runs on Linux as well. Also, the music is supposedly top-notch (I played the game with the volume turned down, unfortunately); they have a
CD you can order with the full soundtrack.
It was also a part of the
Humble Indie Bundle, which was hugely successful. People are still talking about it so your article might get more attention if you include a little blurb about that. The game is also open source now so there's a huge show of generosity from Alec and Derek there, which resonates with the gaming community.
There is an official
media kit for Aquaria so I have no idea why you can't use screen shots to supplement your article.
Other than that, the article is pretty good.
