there is a limit to 10 doubles, then it becomes unstable, you use a combiner on a unstable laser and it becomes green and worth mor
Also, I have tried, the effect where after 10 doublings the laser becomes unstable is not the same as the one I have here. 10 doublings causes the laser to get destroyed after a little distance, in which case it wouldnt get farther than the first corner here.
This is something else entirely. This system is supposed to produce an infinity of superposed level 1 beams.
