Primer: Adaptive Learning is a puzzle game centered around manipulating the game's code-like language, "Primer," to alter the game world and solve challenges. The core mechanic revolves around understanding and modifying Primer commands to affect objects, environments, and even the rules of the game itself. Players are presented with levels where they must achieve a specific objective, such as opening a door, moving an object, or redirecting a laser beam. These objectives are typically blocked by obstacles that require manipulating Primer code.

The game emphasizes experimentation and iterative problem-solving. Players are encouraged to try different code modifications, observe the resulting changes in the game world, and refine their approach based on these observations. The Primer language is introduced gradually, with each new command building upon previously learned concepts. This progressive learning curve ensures that players are not overwhelmed and can gradually develop a deep understanding of the language's capabilities.

A key aspect of Primer is its adaptive nature. The game responds to the player's actions, dynamically adjusting the difficulty and providing hints based on their progress. This ensures that the game remains challenging but never frustrating, catering to players of different skill levels. The game also encourages creativity and out-of-the-box thinking, as there are often multiple solutions to a single puzzle. The game's narrative is subtly woven into the gameplay, with the puzzles themselves often revealing clues about the game's world and its underlying story. The goal is not just to solve puzzles, but also to understand the narrative implications of the player's actions within the game's context.
