Hello everyone!
I'm Jay, the programmer for our duo.
To answer some of the questions/concerns:
For Twitter/Facebook sharing, we don't have a direct button but you can go to Game Center and tap your best score or achievements and then tap Share. If you have your Twitter or Facebook connected in your iOS settings you can add a custom message and post.
I think we would definitely like to release on Android and also a web version for our site. It would just be a matter of getting the high score system in place for each.
Thanks for playing!
