Assess students' ability to design and implement a Scratch maze-solving game that uses loops, conditionals, variables, and custom blocks to navigate levels, avoid obstacles, and track high scores. Require a project plan and descriptions or screenshots of sprite scripts for movement, collision detection, level progression, and high-score logic; specify how loops and nested control flow are used, how variables track score/lives/level, how custom blocks modularize behavior, and how broadcasts or events coordinate state. Evaluation emphasizes correct control flow, modular design, reliable obstacle avoidance, and persistent high-score handling, plus a brief testing and extension plan.
