This is a simple maze generator. The default size of the maze is 30. You can change the size, by dragging the slider on the bottom left corner of the screen. You can press h to hide the "Size of Maze" variable and s to show it. The hardness of the maze depends on how big it is. Good luck! :)
If your maze is somehow impossible, (which is probably a 0.00% chance there is) click the green flag.
