Thank you for your reply as well! I love the idea of an achievement system to track which and/or how many major milestones have been hit for specific character moments! I was thinking about suggesting something of a checklist or roadmap tip section to help players along for seeing all of the different outcomes, but I didn't want to impose considering the already massive scale of the project.
It has been a puzzle for me to test out how to unlock different story moments, factoring in Rael's backgrounds, higher/lower skill levels, and character affinity points. Without behind-the-scenes knowledge of how it all fits together it is a challenge, but the journey is very rewarding when I get to see new text (and especially CGs)! When I am excited about a story this engaging I want to experience it all. So, an achievement system could be useful to track progress as well as let readers know that there is still more to see should they make different choices.
I do so love discovering the minor details, underwear related and otherwise! I am ready to be driven crazy in a good way!! :D
