No, sorry

I might try and learn how to make a smooth animation during winter break.
Yeah, sorry about that. The scene hasn't been added yet. I meant to add the scene or remove that option but tried to rush the update before winter break and just forgot about it. My bad on that.
For the most part, the main/side-quests get grayed out after you complete them (aside from main#2 which is unlocked through main#1 and side#2 which is the 'secret' quest). I don't think a walkthrough is necessary, but I'll see if I can add some sort of 'end of current content' notice.
I'll add a note next update if I put some more secret quests in. Honestly I'm not that happy with the way this one turned out cause the dialogue is pretty basic, the 'talk' options aren't as interactive or interesting, and the 'clues' for the secret quest were supposed to be placeholders. It was pretty rushed. I wanted to add an entire church section that moves the plot forward as well but
Glad you found it interesting though! Thanks again for playing through the game!
