Thank you, very beautiful and interesting level with a good mechanism. The design and idea of the door is really very reminiscent of @Fendi. Spoiler http://mekoramaforum.com/media/trapdoors.27037/ Fendi Removed the first mini version of his level - it looked more like your level. But the idea of your gameplay with balls is completely different, so don't worry. Good level. It was easy for me - because I guessed the correct sequence of balls on the first try
