Wintermute Engine Development Kit is a set of tools for creating and running graphical “point&click” adventure games, both traditional 2D ones and modern 2.5D games (3D characters on 2D backgrounds). The kit includes the runtime interpreter (Wintermute Engine, or WME) and GUI editors for managing and creating the game content (WME tools) as well as the documentation, demonstrational data and prefabricated templates.
