Jaertin, I just updated the Walkthrough link, but it's still only open to my Patreon subs for right now. You get access now for $1 a month. I want to offer the game for free, but I'm keeping the Complete-Guide-With-All-the-Secrets for patrons only, at least for now!
HOWEVER if you're looking for some tips and tricks and can't become a subscriber just yet, I recommend checking out the "WELCOME TO PUTTSDALE: Play and Discuss" forum post on ANIME OTK for free.
THANK YOU SO MUCH FOR PLAYING MY GAME!! It means the world to me and I really hope you enjoy it :)
