Completely rewritten for this specific sub-genre, the Spot the Difference Horror Framework - STAGES, features a robust and simple framework to start building your game.

Premiered by "I'm on Observation Duty" games by Notovia, and extended further by "The Exit 8" by KOTAKE CREATE, this version of the game disposes with security cameras and the time limit, and places the player in the world where he has to explore and discover anomalies in order to advance through the "stages" of the level.

Create any number of levels for your game with the flexible Game Mode and Anomaly System!

The framework also includes utilities for debugging (with example widgets) and a playable demo level with 5 anomalies.
