Imagine the situation:
Passing the game you climb the different walls, which differ from the rest. But at some point in the game, when you're chasing a big troll you are trying to hop on a similar-looking "uzywalną" wall and Klops. It is not possible to climb it. It turns out that the designer at this point has planned something different. Your frustration grows.
Why did this happen? Throughout the game, you have been accustomed to the fact that walls that can be climbed look in a certain way. When dostrzegłeś something looking like you said, rightly, that this rock can also climb. The designer made a mistake-he used the asset that zmyliłed the player.
The designer's task is to ensure the consistency of the game. Fixed game rules should not change without prior notification to the player.
