Just to preface, I actually have played all of your games so far, and enjoyed them quite a bit. I think the reason why it felt "short" had more to do with how there wasn't much of a variation, atleast from my only playthrough of Ep 1. Unsure if there is much to gain from an additional playthrough. It felt very cookie-cutter, in the sense that every scene was just a copy and paste involving the 4 girls. No personality to the girls outside of their looks, and no real hook.
I just meant I hoped you didn't listen too much to people complaining about the "grind" and plan on dumbing it down to braindead sandbox tier gameplay.
I guess my gripe is that I enjoyed the unexpected encounters with the girls that came from entering a specific area, and I didn't really get any of that in my playthrough of Ep 1.
