Escape Plan

I am trying to solve this level but I can't... who has to pass by the tunnel,B or R ??.I suppose B,no??I am a bit lost,any help?

@cpw jajaja,thanks!Now I am at work!! I will try it in the afternoon !! I will tell you...uhhhm,so R has to pass the tunnel,because the tunnel is unidirectional no???

Finally I did it!!! Amazing prison level..I feel like Michael Scofield in prison break jajajaja....The architecture of the prison is simply brilliant and claustrophobic...ahhh,and Thanks @cpw,your hint was the "key" to find the right way

Well I'm lost!

I dropped y'all r down and tried to lift him up, got b to push the ball through getting him in that tight apace but now he's stuck
