I notice you’re asking about — this appears to be a reference to a point-and-click adventure game featuring the character Paula Peril, created by Paul S. Nowak (and often published by Hidden Entertainment or related indie adventure studios).
Below is a quick guide to help you understand the game and how to approach it. It’s a retro-style mystery adventure game in the vein of Gabriel Knight or Laura Bow . Paula Peril is a sharp-witted reporter who investigates strange events. In Hidden City , she uncovers secrets in a forgotten part of town.
