The Google Developer Console is really very very good.
It's logically set out, and makes it super easy to run a Beta test.
I'm on the tenth iteration of the final draft, and think I've got to a point where I can actually promote the app to Production.
The latest revision changed the icon set, and removed a load more cruft, slimming the app down to just 12.14Mb. I could strip out the iOS icons and lose a few more bytes but the original aim way back when I started on this project was to build a simple game that could be deployed cross platform, so I think I'll try and maintain just one codebase... as I really should submit this to the iTunes store too, to close the project.
