Sorry for giving a bad Feedback. Started playing today and only one ceature showed in tutorial mode. Even while walking around nothing happened. No herbs or anything else. Spawning or appearing of creatures should be more often. Gaining experience only while walking around is not very exciting. And no 'button' like Shop, Challenge is working. And I was looking for the Game. I hope that this will change soon.
If you're stuck, and on Android, you can input the redemption code "DELETE-ME" to reset your account and try to start again.
