@D.S.Masters I'll share an explanation in the forum. I have also shared the key mechanism of Yellow King.
I think it's the most amazing level/demo I have ever seen on Mekorama. So surprising and... just magic! I wonder how you first figured it out, if it was by chance or by searching in a dedicate way. Bravo l'ami!
@Gepeto Merci I was thinking about @ArGee discovery, and realised that a remote control could be built. Then I figured out a basic pattern by (a lot of) trial and error. But as any moving block unpredictably changes the whole behaviour of the level, I don't think it will be widely used by level designers.
@vince Thanks. Even after watching it, I'm still not sure how - or even why - it works, but it's fascinating to see.
I'm simply obliged to comment your level: If I think I have seen everything in Mekorama I encounter a level like that. I do not even wonder how you did it. Anyway it will be too complicated. Thanks for your hint n°2.
Great discovery and very fun level. For those that know mechorama mechanics this one is quite fascinating to play.
