I'm stuck at the same spot. Read the whole magazine, and still not getting anywhere.
I have the same issue. Stuck in the cave, read every dialogue, made a hand print, and read the magazine in full several times, including in the room where the whiskey is. But nothing happens.
I absolutely loved the game so far, even though I had to restart it several times because of bugs. But this time, even restarting isn’t helping :’(
Any idea how to get unstuck? I would love to experience the game in full :D
