Hi there! Thank you so much for your lovely comment. I'm happy you enjoyed the game and that it moved you to tears, I'm truly humbled to hear that. Thank you so much! :)
Great questions! I'll gladly answer them. :D
Guide route: Yes, this will be added in the content update. The things that you bring up here are all important points that I'm currently working with to make the route engaging and somewhat believable. I think it'll turn out pretty cool!
After-ending: I have no plans to add that since I feel like it would ruin the mystery aspects of the game, but I feel like *if* there is something else, the couples definitely stick together based on the route you chose. Astrid doesn't know as much in the non-solo routes but she doesn't really need to as she's found peace elsewhere.
Shadows: An interesting thing about development is that we originally made shadows in order to make it so the game could have more NPCs, the plan was that the shadows wouldn't be specific characters but instead just faceless NPCs like you'd see in RPGs for example. But then their personalities kinda grew out of that and now I can't envision them any other way lol.
Thanks again for playing and letting me know how you felt about the game, I really appreciate it! :)
