Hidden Horror Photo Exhibition

「Hidden Horror Photo Exhibition」 is a search-and-deduction game that will send chills down your spine — once you understand what you're really looking at.

At first glance, these appear to be nostalgic black-and-white vintage photos. But lurking within each one is something that simply shouldn't exist in that era. The controls are simple: just observe carefully and tap anything that doesn't belong.

「Why is this object in this photo?」
「What is the true, terrifying meaning hidden behind this photograph...?」

※Button controls are also supported, so you can enjoy it in Tabletop Mode and TV Mode too.
