To contact support just open Pyramid and tap the game screen background, anywhere beneath the cards. A menu will appear at the bottom, along with a Brainium button in the lower lefthand corner.
If you press the Brainium button you'll see a "Contact Us" link on the following screen. Just press "Contact Us" and then select "Yes" to email us! A file will be automatically attached with anonymous app information that could help us identify the cause of any freezes or crashes.
