Welcome to the forum. I gave your level a go and wondered why it made so much noise? I play Mekorama on my computer and since I play music via speakers, the noise is annoying and the motor that was making the noise had no purpose. Too bad you didn't provide a recovery point for B if B was short on the jump (I used a trick to get B back to try again) but only tried twice thanks to the noise. I won with R.
Hi and welcome to the forum. I dislike killing B when it can be avoided. Fortunately you left him a stone block on the short side of the level that he could use to knock the ball slightly sideways so it rolled into the hole by the win between the motors. B then just turned R (who can walk on a ball after going down a stair) so he could find the win.
