You're going the wrong way if you don't encounter opposition
There’s a reason why variants of the quote, "if you’re not encountering opposition, you’re probably going the wrong way" get thrown around in so many circles; it applies to nearly every game in existence. Whether it’s a slew of enemies being thrown your way or increasingly difficult puzzles, games have continually taught us that progress rarely comes unhampered. If you’re coasting along and never being challenged, it may be that you’re simply retreading old ground. Even if it seems impossible to continue, chances are that the only way to move forward is to determine some way over, around, or through.
