Very nice design. When I saw it, I immediately really wanted to play. The gameplay is easy but interesting and in a classic style - I love it! Thank you. I enjoyed it. Since you also love beautiful design and strictness in symmetry. I want to share my experience with you. For example: let's say you want to have full symmetry, but for gameplay you need to have several openings-windows closed (like in your level). Let's say you don't want to change the gameplay, but really want to have symmetrical openings-windows. There is a way out - a fence! Spoiler It blocks the passage and visibility, but leaves an opening-window in the design))). This is just an example - maybe my advice will come in handy in the future) I sometimes puzzle over this for a very long time.
@Denis Nazin Wow! Thank you very much. Your hint are really important for me. I was thinking on a more complicated level with the same principle as elevators. So I will surely use your advice.
I love the way of your designing 'cause mostly when I construct big palaces like that I get so annoyed and I just hate it sometimes, but your level is a nice one with good logic.
