I use it depending on whether an otome game or its route is interesting or not for me, if it interests me then I won't use auto mode and when it's not that interesting or for me it's boring then I usually use auto and let it run and I do other work at the same time
sometimes when i'm doing something else like eating or drinking while i'm playing, which is rare, i put the auto function but other than that i don't use it lol i read fast and like to skip hearing the voices, mostly for the npc, unless my favorite seiyuu is talking lol xD
Nope. I enjoy to reading the storys at different speeds throughout. Whichever dialogue I like, I'll repeat to read it over and over. It takes a long time to finish one route
I rarely use the auto-play function because I prefer reading at my own pace. Sometimes I want to pause for a moment to enjoy a line, a CG, or the atmosphere of a scene before moving on. I feel more immersed in the story when I can control the flow myself instead of following a fixed speed.
Most of the time the auto-read function is TOO slow! like why are you making me wait a whole minute just to read one sentence? lol. The only time I use it is when I'm eating a snack and my hands are busy. I know that there are settings that lets you change the auto-skip speed but I don't think it's in every visual novel, which is a bummer.
