Wasd to move, Mobile controls self explanatory, Gray circle for settings, The lower line size is, the higher the resolution. This game can run very slow on lower end computers and at higher resolutions, so I recommend play on turbowarp here: https://turbowarp.org/558778891 You can make your own custom maps just by editing the map sprite to whatever drawing you want
So basically how this works is that when you move it broadcasts a signal that tells the dist scanner whenever it touches a wall of the maze, it broadcasts another signal that tells the pen to draw a line. I way oversimplified that so take it with a grain of salt lol
