Thanks, @Block builder, @Don G Rowe and @cpw. And @cpw, I thought that the forum already has a lot of B levels that can be solved with tricks and whatnot, so I wanted to do something a little bit different for the moment...
Incredible logic/ability level and at the same time a really annoying one. Thanks! Spoiler: By the way... I didn't solve it crossing the middle corridor but grouping both Rs in last stage beside the win and with right timming and ability one of them turned right to the win, is it right?
@chemi I actually found 3 ways to solve it, including the one you mentioned. I didn't want to close the different paths because most of them have a similar number of steps.
Nice and not too difficult I thought first it would have been more complicated but requires me maybe 30 seconds to see it solved. But I really enjoyed! I just wonder if this is the intended way but on such puzzle I would be surprised that there is on one solution. Thanks dude!
Very nice and original level with Rs as the protagonist!! The design is cool too!! Thanks for sharing and well done @Chuckthulhu
