Great game! Level 10 became hilariously complicated. By the time I was done, my robot acted like Microsoft Windows. It performed a million steps just to light up two pixels.
Very neat game. I got past the hard levels (16, 19, 23) by thinking outside the grid, and just trying to connect alike colors to each other with "wires". However, the wires are not allowed to overlap each other. Not all solutions like this worked, but it does narrow down the choices alot.
