The tutorial doesn't progress until you give input, but since it can be anywhere, it's very easy to accidentally advance it. It would certainly be better to do it another way haha.

SPOILERS AHEAD DON´T READ BEFORE PLAYING THE GAME
Also, answering your first question, is a bit of both. There is a ""right"" (understanding it as what Sito, wich is clearly unreliable, believes is the truth), answer for (almost) every question, but neither you or your character have any information to responding right to them. That´s completely deliberate, and gets explained why in the "last day". It might be too confusing at times (at the end is hard to write this type of stuff with this little time and external testing), but at the end that´s the idea behind the game.
