I tried and tried but can't do it. I like the design but it suffers from the dreaded slider traps, where B falls into the slider and can't move. All he can do is fall off sideways. There are three of these slider traps - the two rising to the top and the one in the roof. I went up the left slider to the top and found it near impossible to stay on. Then when I did make it into the roof B fell into the slider there and I couldn't free him easily at all. Also the sliders knock into the windmill blades going up and down. I do like the way they can be stopped with the blocks though. I tried again and reached the roof but then found it impossible to get past the windmill! I had to give up. Visibility is also tricky, it's hard to move some of the blocks due to the walls. I think it's a clever design, and I really want to win, but it's too difficult for me.
Thanks to @Chris Hester, I was able to anticipate the problem with the sliders & was able to win easily. Thanks
I really like the design!! Very beautiful. Nice to explore all the ways. I don't really like when B walks on the slider and drowns in it. As far as I understand at this level, this is a special additional test. You can quickly run - then B will not drown in the slider. Thank you. I really like the architecture and intriguing gameplay. Therefore, I believe that one of the players should put 5. It will be me
