“how much of homestuck is improvised as you go along? or does it follow a fairly strict plotline you’ve written out beforehand?”

It’s a blend of foreplanning and spontaneity. Maybe in roughly equal parts, but this is a thing that’s really hard to measure.

I’m going to accept this, because it is little known, but yes, it is important. So here, have this little known fact.
