Unfortunately after 5 attempts I gave up as your B toss / rotor arm was extremely rough to use. When Motors hit another block like the red bricks in this case the motor doesn't work well.
I brought your level into MekoStudio and gave it another go with the 2 red bricks gone. The motor worked nice and smoothly and B did escape but not on B's 1st attempt. The B toss didn't work on my 1st attempt but B was able to slow rotate and try again. I can't rate as I didn't play the posted level.
It's true that it's a bit easy but I see that this is your first or second level so I believe that you can ADD CHALLENGE AND DIFFICULTY to your levels and do great levels....Uuhhmm,can you beat me? Waiting for future challenges...Thanks for sharing and well done @ drunkapple
