Maptographer is free and simple, yet powerful general purpose tool for creating map, map elements with embedded data for any type of 2D (or even 3D) game such as roguelikes and RPGs. Maptographer can be used as a to extend current dungeon generator possibilities by adding new user-defined layouts. Note that this feature is not yet alive, and it will be available from version Alpha 9.7.
The tool itself is not limited to use in extending the DoE, it can be used even as separate asset creator for any other game out there. Beside graphical data, every asset can have various data appended to it in form of strings, number, floats, booleans or custom 2D,3D and 4D vectors. Asset loader will be provided on GitHub for several languages (C++, C# and JS planned).
