This gradual accumulation of knowledge is almost the whole of Blue Prince (one early room recommends having a notebook at hand; I filled several pages), although there are some architectural elements of the house that become permanent, making future runs more likely to be fruitful. These moments tend to feel big, some of them even having very atmospheric cutscenes that break up the routine of drafting door after door. You’ll also be collecting passwords and codes that stay the same across runs. Mainly, every new draft is a question of what you will learn about the estate and how you will apply that knowledge in future runs.
