Dear Almakos, Thank you for making that video, I checked and found that crash because you have earned a bronze medal at a very first time, then the game offer a method to ask you if you want to share on facebook. Next time you reopen the game then everything should be OK I will fix this in next build . Thanks again man.
Thank you for playing my game. I have just updated the game, the new version: Enjoy the game and thank you for your feedback!
