What is the primary goal of the project that involves Karel making towers?

The primary goal of the project involving Karel making towers is to provide a creative coding challenge. This exercise encourages students to apply their coding skills while engaging in a fun and imaginative task. Building towers allows students to explore concepts such as loops, conditionals, and systematic programming while fostering problem-solving skills. Through this project, learners can experiment with different approaches to achieve the desired outcome, which enhances their understanding of programming in a playful context.

In contrast, other options focus on specific aspects of coding rather than the overall objective of creativity and engagement. Enhancing Karel's ability to turn may be a minor component of the project, but it doesn't encapsulate the broader goal. Limiting coding complexity or decreasing programming time are practical considerations but don’t align with the primary intention behind making towers, which is centered around the creative coding experience.
