This is a simple little program. You can make walls, or you can... not. Whatever. Push space to start the square. It will keep going, looking for the fewest number of steps to every square. The timer at the bottom resets if the square makes any progress. IT TAKES A LONG TIME TO MAKE PROGRESS. Also, you can hold shift and push the flag to turn on turbo mode. That might crash your stuff though, so be careful.
