Pathfinding Demonstration

This is a demonstration of my pathfinding algorithm, using a breadth-first search implementation. The numbers on the tiles and corresponding shading represent their distance from the endpoint.

Instructions: 

• Left-click on any cell to set it as the endpoint of the path.
• Right-click to toggle whether the cell is passable or blocked. 
• Hold shift while clicking on a cell cell to set it as the start point of the path.
• Use the buttons below the grid to change the color scheme of the heatmap for better visibility.
