Finally beat the secret ending to SE. Holy shit I have never seen and will probably never see such an intricate and challenging puzzle in a video game ever. I'd be interested in seeing a ranking of video game puzzles in terms of mathematical complexity (rather than obscureness) and I imagine SE's secret ending has to be up there. What's neat is that the solution is randomized, and even if you read about the solution in exhausting detail you'd still need to understand it and then unravel your particular shuffled answer.Looks like I've got a few months to finish K2SE, lol.
I had two goals with SE, first was to get the secret ending and second was to have a (relatively) steady state factory with a high SPM. I'm going to start cleaning up a few loose ends now, but the end is near.
