Click the green flag and watch The Box Builder's ant work hard flipping tiles until it touches the edge (at 11340 steps). I spent too much time on this.
It uses three different actions: Turn 90 clockwise when it's touching white, and 90 degrees counterclockwise when touching gray or black. Creates "Streets" meaning the only bridges it builds end at some point. Thanks to papipupepappa for the OG project.
