Your friend is missing and the last place she visited was this shop. You have to go look for her.
This game builds on "Night Terrors", which we played many months ago. Fortunately that didn't matter since it was only the story that made a bit more sense since we had played the other game. You could still have a great time without playing the prequal.
360 degrees view of the room and a few navigations to look behind the counter. Telescape based. We did not like how they handled inventory. It was the main page and static so annoying to navigate to and you couldn't do cool things there.
Puzzles were great though we did find a counting puzzle a bit tedious (what counted and what did not?). Quite easy but that just meant that you had progress all the time. Nice acting in the in-game videos. It is a bit creepy mostly because of the story-line and theme, but nothing really scary. I would probably not play this with young children though. There is nightmare-building props all around :).
We would recommend this even if you haven't played Night Terrors.
