Great R puzzle! Compact and simple, but puzzling. These types of puzzles are growing scarce; it's great to see that they're not completely gone! It goes past the 5th block height while playing, though . Thanks!
I think that rule only applies to the start-state. All nxnxn levels have bots walking on the roof at some point. You can also walk at z=17&18. (and x,y = infinite for that matter)
Thanks for the rating @Frenzies! I wanted to create more puzzles after the recent wave of tricky levels And thanks @AlexSGE1980, I'm glad you liked it!
I love this design! It's really great and brief, only using small space. You built this level based on R's nature habit, I like that! Thanks for the wonderful level! I enjoyed it! And thank you for rating @Ricko 's levels too, it's not only a deal for me. I am glad to play another great level!
Thanks @Wang Hung! I built this for a challenge and we could only use metal blocks, I'm glad you liked it and thanks for the nice review! . And @Ricko is my friend too, so I always play his levels I just don't always solve them...
@Chuckthulhu Yes, some levels of @Ricko 's are very tricky, I am still stuck in there... Actually I am not very fond of complex and big levels, I am always too lazy to observe the terrain and the way it works, so sorry for playing your level only when you ask me... Anyway, thank you!
