So before I get into this, I should note... I was high during that stream. Since streams are just meant to be fun for me, I usually consume a bit of cannabis to help me out. This doesn't affect my ability to give feedback, but it CAN affect my memory if something isn't explicitly stated.
I'm going to check through the tutorial again when I'm not high to see how it teaches things.
That said, it was a bit of both for me. For now, let me cover in terms of the first guess...
When the game starts, there are a few lines of dialogue to get you started which sets a vague goal but gives no idea of how you achieve that goal. You're just thrown to this big world with no guidance of what you're looking for, both in the immediate and long term. This could be your intent, but for me it makes it hard to enjoy when I don't understand what I'm going after. I'll try and use an example to explain what I mean.
Let's say this was an MMORPG instead of the game you made. Normally, when you start a new character there's a quest to give your initial direction of what to do or where to go. In the early stages of an MMO, it's never going to stay with that as the goal but it gives you SOME idea of what to do until you figure things out. In this example, this would be the equivalent of a quest giver going "You have to save us" and then you're told nothing about who you're saving them from or what you're supposed to do. Who are you fighting? What are you supposed to do for the quest? They won't give more info, and all you can do is stumble around until you accidentally find what you're after.
And it doesn't even need to give a direction to go, so long as it sets a goal. Like, going with the dialogue you offered, I would say this is what should follow in narration.
"The people of your city call out for help. You must find a new place for your people to live, but there are threats everywhere. You must both grow your army and yourself stronger in order to lead your people to whatever this new home may be."
That idea at least tells you "Ok, so start doing random fights. You want to get recruits for your army and grow your own power while you seek a place far away where your people can live in safety." It doesn't specify what this place is nor the direction to go, but it DOES set a starting goal for the player while they figure out how the game works.
