Hold to Release

Looking at the caption i see i made life hard for myself. I had a lot of wild swinging of the slider arm to get it as i wanted. Then i got so focused on it , i was using it when there were easier options. Then thought i might get quick win when i dropped R onto sand blocks thinking he would turn onto the cylinder after the step- nope. I used R for both the high balls. Strange that one ball seemed to have no purpose as i was sure it would have.

@ridgerunner - I'm glad you succeeded... I thought the level was a fairly easy one to be honest but I did create it and I may be bias. Thanks for playing, commenting and rating.

Hmmm. Second ball is annoying as B easily touches it such it rolls the wrong way. And it's actually not required. To get B to the middle floor to push the third ball you can drop him and use claustrophobia twice and a small autopilot over a wedge in the corner. The fourth ball is also annoying. Mostly it will not require B, but then sometimes it does. A reliable ball path is more preferable. And then the end is annoying as also visible in your video. Bot stickiness is a common thing and such close bot moves should be avoided. This one is not for me.

@Block builder - Too bad it didn't work out for you .

Very nice level and I was surprised when I noticed that the arm was very easy to control... Thanks for sharing @gmacpro
