The game for Android! As soon as it's released! Also, the game for iOS, as soon as that's released, AND exclusive access to the (ugly but functional!) online Flash prototype, so you can start playing it immediately (albeit without all of the features) on your PC!
Do you fancy yourself an artiste? At this level, you can design one of the graphical “skins” for the game (as long as it's “PG” and all artwork to which you own the rights or represent the rights-holder)! You can also either provide the accompanying sound effects for your custom skin, or we can create some for you. And, of course, you'll be prominently credited, with an optional link to your website.
