Whenever I try to launch the game, it just crashes. This has happened since I updated, rendering the game unplayable. I have checked this on my iPhone 6 running iOS 9.1, and will check my laptop to see if it happens there as well.
Update: So I restarted my phone and that fixed it, but this should still be looked at as a bug in my opinion, as other users are reporting similar things on reddit.
Please respond and add the current version if you can reproduce this issue.
