MAGIC MANSION

This puzzle is a bit complex, and must be done in correct sequence to complete, but the payoff is awesome ! Hints: drop the elevator catwalk, and "roll that roof !"

A very beautiful and expansive design. An interesting level.
But! There are a lot of shortcuts. I think I got all four stars (except the central one) without planning. Because you have so many move-elements, two stars can definitely be gotten without bots (just rotate and position the slider under the star)

Spoiler

By the way, if you use brute force, you can get the remaining two stars without using bots! But that's not correct, so I used a different method.

. The remaining two stars can also be taken by shortening, since there are a lot of bots on the level (you don’t have to use B) and also take two stars by rotating and placing the slider with the bot (Z or L) on the slider under the star.
My advice for the future: try to use fewer moving parts and bots (try to keep the number of sliders, motors, and bots to a minimum!) - because there's a very high probability of MANY shortcuts! Otherwise, you need to do a LOT of testing and level checking. But even VERY experienced builders make mistakes. And they don't notice shortcuts with a large number of elements and bots! So the universal way to avoid this is to follow my advice.

Despite the shortcuts (shortcuts for stars), I still enjoyed it, and I found this level to be fun and adventurous enough to give it a 5.

But in the future, please consider my suggestions and advice, because shortcuts can lower your rating or even cause you to lose it altogether (since a level with shortcuts is considered unfinished and hasn't been sufficiently tested). And players won't be able to enjoy your correct route because there's an easier shortcut.
But I really like the design and the hard work you put into creating this level, so I'll appreciate it despite the short paths.

I agree with @Denis Nazin 's comment about the move-elements & how they allow a lot of shortcuts. Due to this fact I have a lot of doubts about the intended solution although I only took one star without B, just moving accidentally one of the move-element. Very nice design, btw. Thanks @FUNATIC & I honestly think you should heed the advices of one of the best creators in Mekorama history
