Just type your preferred tile size, and if you want to see the maze actually getting generated, and the generator will do the rest.
If you input a non-numeric value in the first question, the maze will just look like a small crosshair in the middle of the screen, and not much else. Changelog: Ver 1.1 - Added the ability to regenerate the maze by pressing “r” after it has finished generating. I also fixed the bug where trying to input anything lower than 20 would lead to it not working. Ver 1.2 - Press "T" to show how many mazes have been generated in total. Press it again to hide it.
