[2] The software was originally called "StencylWorks" while in development and for the initial release but was later shortened to just "Stencyl".

The application includes several modules used to accomplish the necessary tasks to create games with the software.

Alternatively, Design Mode is a GUI that allows users to create modular game logic for actors and scenes using a visual programming language.

The concept of Design Mode as a form of end-user development originated with MIT's Scratch computer language learning environment and was used with permission for Stencyl.

These blocks will snap in place together and nest within each other, permitting the creation of advanced logic from basic components.

Its use in Stencyl is usually secondary, as images are typically imported directly from the computer after being created separately.
