Map editors, level editors
A level editor (also known as a map, campaign or scenario editor) is a software application used to design levels, maps or campaigns for a computer or video game. Sometimes a level editor is integrated in the game, and is an integral part of the game. Other times (and most often), it is a separate part of the game.

Herbert.NET
Herbert.NET is a library for the Herbert game, written in C#. It has full support for the H language including the execution of H programs. Levels can be created from code or loaded from files. In addition, the visualizer can graphically display levels and control execution of H programs, with various options for playback and display.
The interpreter may be used for creating a simulator or any other purpose. It is a standard .NET 3.5 library and therefore may be used in any VB.NET 9.0 or C# 3.0 project. The visualizer is intended primarily as an aid for solving levels manually.
