If time is merely an additional space dimension, why do we experience
"moving" in it always and only in one direction? Why do we remember
the past and not the future? Could a being move in some spatial
dimension in the same way we move through time, and in doing so treat
time more like we treat space? Et cetera.

To my knowledge, modern physics treats many things as "dimensions":
not just time and space, but also forces such as electromagnetism.
This does not imply that such things are spatial in nature. A
dimension is just a variable. Unless you think there is something
particularly spatial about time?
