Good to see you guys helping each other out - that really helps me out with my workload :)
I've updated the plugin to introduce a new loading splash. You can turn it on by enabling the Clay.io plugin property: "Use Clay.io Loader". I think it looks a bit better than the standard loader, but it also benefits Clay.io some since it links to the marketplace (we're trying to grow the consumer side to have much more traffic).
The orange HTML5 logo will be your game's logo if you have that set in the C2 properties.
Let me know what you think!
