Nice level - I started off saying 'good old hidden once again' as R went around and around so I restarted and didn't drop the ball. This time R raised. Upon winning, I restarted to try my 1st way and R did raise with the ball dropped so not sure if the mechanism was broken or slow.
The R Ball step is nice! and quite clever to implement it like that I taught it's maybe R is unstable then I saw the way why its jumping and falling off
What is R supposed to do once up on the 4 metal square tower? Mine just wobbles a bit & does the usual right turn circuit around the top. Three times.
