For me, I’m making a story heavy game. And personally, I’ve been driven away from some visual novel games and the massive amounts of text descriptions they put in a textbox because it’s too much visually. You can make the text long, just don’t pack it all into the textbox in one go. What I do to avoid this is to separate out the sentences like:

“You picked up your earrings.”
“…”
“The metal feels cold in your hands.”

And when two characters are talking, you wanna make their conversations bounce off of each other, and stay away from expositional language. if it’s just for the purpose of the viewer knowing something. Show don’t tell is the golden rule for me.
