Hey guys! We have finally added a so long awaited e-mail and Facebook login features to Steam client. Those who wanted to share the same game account on their mobile devices and on Steam now have such capability. The only limitation is - currently we have deployed this new login scenario only to Windows version of the game. We plan to deploy it a bit later for other platforms too. If you played on Steam and want to play on your mobile device you need to: 1. Login using "Sign in with Steam" using Steam game client. 2. Go to game lobby screen. 3. Open settings window. 4. Turn on "Bind to Facebook". 5. Login to your Facebook account. 6. Now you may quit the game on your PC and enter it on your mobile device. You will have to use "Sign in with Facebook" to see your Steam character(s). If you played on mobile device - just log in the way you entered the game on your mobile device. We hope everything will go smoothly, but we are still working on improvement of this feature. Have fun!
