Well, the 'problem' with the Emi-route is that at first it is rather smooth, but you can expect things to get a bit more dramatic.I'm trying this, am on the Emi route (although I probably wouldn't choose her if given a choice). Around 2-3 hours in. It feels a bit stagnant. Am I just not the target audience, or does it pick up?
I should add that I wasn't looking for a quick fap, lol. I watched A Silent Voice (amazing movie) and looked for a similarly heart wrenching experience.
Also, i generally suggest at least considering to use the flowchart to see different endings for the girls even after seeing one of their endings... i personally did so for 2 of the girl's stories from the get-go after playing a while (reading it suggested somewhere) aiming for the bad endings first. Made all the endings, good or bad, more impactful for me.
