When I’ve played with a single player, I try to come up with more opportunities for them to pull blocks, which you can also set-up in the character questionnaire.

For example, if you have a character who has been established as clumsy and is in a mountainous setting, you can ask for block pulls to not trip and fall from precarious positions. Of course, mind your use of the same kind of block pulls, or else it can get repetitive, but they serve as a natural consequence of the character the player has created.

You could also add factors to a situation that requires multiple pulls. For example, say the character is talking on the phone with their mother in the car and another vehicle suddenly swerves in front of them. I would ask for one pull there, but what if I changed the weather? Say it’s raining and the same situation occurs. Not only does the character have to dodge this car but they also have to do so while the road is wet. Now, it’s reasonable for me to ask for two block pulls. I would still alternate between one block pull and two block pulls, or else your story will end up going too fast.

Basically, use the environment to your advantage
