Puzzle Creator

The Puzzle Creator (also known as Puzzle Maker or Editor) is a part of the Perpetual Testing Initiative in Portal 2, a DLC released on May 8th, 2012 allowing the creation of single-player test chambers within a simple in-game editor.

Overview
The editor was first mentioned within The Final Hours of Portal 2, "[An in-game level browser won't be of much use unless] Valve figures out how to make designing Portal 2 maps an easier process. It has a plan there too, it comes in the form of a simplified level editor [...] a Photoshop for test chambers".

The "Puzzle Creator" does not appear to have a single official name; Valve published a blog post on the October 27, 2011 referring to the editor as the "Puzzle Creator", later referred to it on the blog post of April 27, 2012 as "Puzzle Maker" and simply calling it "Editor" in-game.

Interface
The Puzzle Creator features a stylised representation of the test chamber being worked on; featuring a simplified, bright, and flat color palette, and models and textures lack the level of detail that they would have in-game.

Limitations
As the puzzle creator is designed for ease of use, certain limitations apply. These limitations can be overcome by importing the map into Hammer in the Portal 2 Authoring Tools.
 * The entity limit is set to 1750; the actual number of items placeable by the user is much lower than this.
 * The editor is block based, so complex geometry such as curves and angles smaller or greater than 90 degrees cannot be achieved.
 * Chambers are isolated, so sequences of chambers cannot be published as one map using the Puzzle Creator alone.
