I personally love that there are encounters you are too low level for, but can attempt.
Too many games these days has this hand holding aspect, where the enemies level with you, and that combat should always be winnable etc.

We are playing the game at the medium difficulty right now. And the game isn't all that difficult, but some fights are tricky. Which is a decent place for a medium game to be. So yeah, if you struggle you can load the game, go explore other paths, and come back later. That's how we used to play RPGs back in the day.
