A build is a version of the game that is compiled and ready for testing or release. It represents a snapshot of the development progress.

Concept art sets the visual tone and style for the game, illustrating characters, environments, and key moments before full production.

Playtesting involves real players trying the game to identify bugs, assess difficulty, and provide feedback for improvement.

This refers to the making of all the visual and audio components of the game, such as 3D models, textures, sound effects, and music.

The codebase is the entire collection of source code written by programmers for the game. It's the foundation upon which the game runs.
