Today I wrote code to remove walls. The buttons 3, 2, 1, 0 you see on the toolbar move the blue dot in one of 4 directions, and is used for testing. When the blue dot, which denotes the current position, moves from one cell to another, the wall that separates those two adjacent cells is removed.
Tomorrow, I will write the maze constructor proper. For the algorithm, I intend to reuse the code I wrote during Amorphous Maze project.
