It does for the most part - just trying to figure out some issues it has with Android devices, and scaling of the user interface elements, then it should be good to go.
You can follow progress here: clay.io/members/community
The reason you get a black screen is you have to copy over the following files into the .zip Construct 2 generates (you can find them in the Clay.io plugin folder):

Ok... I can not find the logo.png or the c2runtime.js file in the Clay.io plugin folder. But I drove one with what I have but, the problem now is the game on my ipad will just freeze on changing to the layout that has the clay.io show leaderboard on layout start. But it works fine on my desktop on google chrome.
What could be the issue? Can you upload an example file that you know works. Or possibly provide your Clay.io Plugin?
