In-game level editor

Software concept

The construction kit or similar works in-game rather than as separate tool, often adding a layer of control on top of the game rather than a separate editor, making level testing simpler and faster while maintaining familiar controls.

Alternate names: In-engine editor, In-game construction kit

The first video game about In-game level editor was released in 1981.

Note that the editor may in truth be separate application, but works in similar manner as the regular game and can be used to play as well but is likely more demanding on the system due to the editing tools being part of it.

This is NOT for instances where the editor is accessible in-game but works like a separate tool.
