I think I've seen this before when testing on the virtual Android. I was able to resolve by waiting a bit more and tap on the screen. It may take more time to load the game at start. I can test again to make sure things are working in Android.
I need to put the cheat descriptions in the release note so that people know what cheats are available. Otherwise they won't know what they're signing up for.
Please excuse me I'm using Google translate. Is this on Android? I tested on a virtual device and was able to pass the battle tutorial as well as the first quest.
If you have more information it make it easier to help. Even a screenshot would help a lot.
