YMMV / Secret Files

• Paranoia Fuel: The final battle in the second game involves Nina needing to outmaneuver Shelton as she scrambles up and down a building. Each floor, she needs to figure out what to do but take too long and Shelton suddenly walks out of the stairs and pulls a gun out and fire, forcing, Nina, the player character to another floor. It's even scarier if you remember that you could get a Non-Standard Game Over before if you approached Shelton too carelessly.
• That One Puzzle: The game has been known to have very unorthodox solutions to inventory puzzles that reviewers even call ridiculous, leading players to guess all combinations of items and environment until they get the right one for reasons they don't even realize. But the most notorious example of this is when you have to tape a cell phone to a cat and guide it into a man's kitchen to record his conversation.
