for these wondering why they cant medium badge, cut conter is kinda broken(might be intentional), instead of counting slices it counts your attempts to slice, so every time you enter shape in cut mode it just +1
to guy with alternative solutions, the problem is not that algorithm is bad, its the fact some of pixels get squished out of window and wont change colour, try to repeat level with the same combination; and to devs, add wall around level layout so pixels won't run away
