The tutorial is breakable in a lot of ways. For example, I was able to fail Orik's roll for the Soldier by switching to Charisma or Diplomacy. Later, while fighting a goblin I received a message that I could use the Soldier I did not acquire to explore again.
If Orik does not use the Soldier to explore again, when Ameiko encounters the Codex, the game claims that Orik has an ability which can help her obtain the item, which is not true.
On another attempt through the tutorial, I killed Ameiko off early and had Orik continue on. I must have missed some events because I closed the farmhouse, but could not move anywhere else. Initially I kept getting messages that the action bar was not active during this point of the tutorial, and now after reloading I can look at the map and end my turn, but Orik still cannot move to another location.
After killing Orik in an attempt to progress, I have completed the tutorial portion, but have not unlocked Merisiel or Kyra. The game gets stuck at party selection until you quit, at which point the tutorial restarts.
The tutorial message describing bar icons has an Icon for 'move to a different location' which is different from the icon located on the bar.
