World of Spies is a spot-the-difference game built with Godot for Pirate Jam 18.
Each round of the game starts with 60 seconds on the clock. The goal of each level is to find the anamoly in a crowd of similar looking characters. Each correct guess advances the level and adds 5s to the timer. Each wrong guess resets the level and deducts 5s from the timer. As the level goes up, the crowd grows, making it more difficult.
