📖 Our Story & Concepts
Maps and mazes use directions to guide travelers: forward, backward, left, and right. In video games and robotics, a computer screen is like a giant grid of tiny squares. Moving side-to-side changes the X number, and moving up-and-down changes the Y number.
By connecting keyboard keys to directional movement blocks, you create an interactive controller. You decide where the character goes, step by step, solving the puzzle using logic and spatial awareness.

⚑ Extension Challenges & Blueprints
- Level 1: Add hedge collision detection so the puppy cannot walk through the green maze walls.
- Level 2: Place a golden bone in a corner; when touched, play a bark sound and hide the bone.
- Level 3: Add a step counter variable that counts how many arrow taps it took to escape the maze.
