Wow!! Amazing tricky level!! And difficult!! I did it like you except the first step...I think that my left meko-brain is a bit insane...I tell you... Spoiler Obviously I knew I had to "unhook" R to use it and I did so: when B turns the wheel stays a little up on the side of the bow ... then with the precise timing I have tapped on the moment when the wheel and R block to B and falls to the stairs .... buff, how complicated, no? The design is very very nice too!! Great challenge and great job!! Thanks @Block builder
