# Forest, how to specify distance between levels

I have this code, but want to reduce the distance between the levels. Any suggestions?

\begin{forest}
for tree={
circle,
draw,
fill,
minimum width=2pt, % size
inner sep=0pt,
parent anchor=center,
child anchor=center,
s sep+=25pt, % distance between children
grow = north
}
[
[
[]
]
]
\end{forest}

The level distance can be adjusted using keys l and l sep. For details, see the sections 3.7.2 (reference) and 2.4 (tutorial) of the manual.
