Can you tell me how to go further, I'm stuck on hide-and-seek quests, dead girl taking and making friends. I can't find any other quests(
-hide and seek quest is likely done. Once you find the little girl in the infirmary that's it for now.
-not sure the issue with dead girl talking. What's the current task and her current state (IE is she still tied up)
-This is likely your block. Have you done the werewolf quest yet? You'll need to click on a bush in the park to initiate it.
