Looks nice, but too bad you can't run different pathfinders on the same maze. Running on an empty grid is default but it's less interesting to me.

+1 for this. Would love to compare all the algos on the same maze, so you can visualize the differences in their pathfinding approach.

Yep great idea will try and update the logic to implement this !
