  1. I followed your walkthrough, but for some reason, I couldn’t unlock Demento’s first CG. What went wrong?


  2. Thanks for these walkthroughs! I’ve been using them on my playthroughs of P:C and they’ve been a huge help. They’re easy to follow and are spoiler-free, which is exactly what I was looking for ^u^ Thank you!

    Just wanted to point out right quick one thing I noticed while playing. For the 4th last choice of Demento’s short route the options are “I’m just curious” and “I’m genuinely interested,” of which the correct choice is “I’m genuinely interested.” As your option has it phrased “I’m genuinely curious” it was a tad bit confusing for me when I was playing. A simple speed-typing error, I’m guessing…?

    In any case I’ll definitely be keeping an eye out for any of your future route guides! Do you use any Japanese walkthroughs (like choro’s) or do you write them yourself?


    1. I’m glad that my walkthroughs have been helpful! I try to keep them spoiler-free because I know the feeling of looking up walkthroughs half way into a route, and getting spoiled which ruins the whole storyline. Oh, thank you for pointing that out I probably mixed up the options when I was typing it. I’ve fixed it now so other people won’t be confused by it 🙂

      For Period: Cube then I wrote the walkthrough myself, since the game was fairly straight forward past the common route. I do try to write them myself because I usually like to play efficiently. E.g. I know other walkthroughs for the bad ending suggest playing from the beginning and choosing the opposite answers. But for when I played it, using the history option instead in P:C saves a lot of time 🙂 If I do get stuck in other games, then I do look up and read the japanese walkthrough for the part I’m struggling with.
