GGJ is coming up, is HTML5 ready?

Global Game Jam takes place at the end of this month, and I was curious if the HTML5 capability of Corona is in a “good enough” state that I could take a crack at it for the jam?

Any specific issues or gotcha I should look out for? 

I did a Corona HTML5 project for last Ludum Dare and apart from almost messing up with Lua file system (not a HTML5 specific issue), I had no issues then. The only issue that comes to mind is that apparently the images are rendered blurry (due to upscaling iirc) for HTML5.
