Updated to newer version of Unity Engine

Now the game is in a bit newer version what should help a small number of people who could not open the game. Tell us if this helped you (make sure you update the game, version is v0.727 or higher when we update the game some more). Or of course if you run into any issues in new version. From what we tested so far it is working well but with many people playing we can never be 100% sure.

Thanks!
