Castle escape

B is in a dream he needs to get out of. To do this, he needs to go through a special portal in the castle. But there's this guard that first needs to be distracted. And the inside of the castle is such a mess.

Thanks to @Meko Guy for reporting a shortcut in the previous version. Also fixed an additional shortcut in the 'mess'.

Very beautiful design with circular symmetry. This is a "3D traffic" style level. I like the idea, but in my opinion the visibility is a little poor (this makes it difficult to see all the traffic and build the logic). I only managed to win with one bot, because for some reason my LZ accidentally went astray and returned to its original position. After that, you can reset it instead of B. But this is probably an accident.
For the wonderful design, 5 from me. Thank you

@Denis Nazin one side is indeed a bit dark. But I think you could built up a mental model of the space. There are roughly two section with very little interactions.

Regarding Z going down to the balcony, did you play the first or second version of this level? You can recognize this by the top corners of the castle.

Thanks for playing and rating!

Excellent puzzle,excellent design & fun storyline... last night I solved the level but I was not satisfied cause I was distracted for a few seconds and suddenly I saw that ZL had gotten off his route down the stairs and I won without using B... that's why this morning I played again and I was able to enjoy the complete gameplay... and reading your reply to @Denis Nazin I have verified that I have completed the first version... thanks for sharing @Block builder
