I have Aphantasia, and it has a lot less impact than you might think. Just like you I’m able to retrace steps in my mind, or to imagine objects, or recall visual facts from memory (E.g., tell you the colour of someone’s hat, or the shape, etc), or to solve a maze in my head before drawing it on paper, etc, etc.

Pretty much the only thing I cannot do that people with Phantasia can is picture images in my head. E.g., I cannot picture a cow and then rotate it in my mind. I can imagine the concept of a rotating cow, but there’s no head picture that goes along with it. Other than that, I cannot think of any real task that is in any way more difficult (or even really different) from people with Phantasia.
