Dropping the ball beside B after getting Z in place is a real pain - I got it after three attempts so not sure if I was good or just lucky. The two Rs starting bumping in the corner trying to get them out and there's no way to control them. Having a R freeze slider in the corner for the ball and getting the bots up the stairs would have helped. Overall - an annoying level with too many restarts. EDIT - Using Mekostudio, I setup and worked out the timing and it wasn't easy. With Mekostudio, the pain was removed as I just started where I failed without restarting from scratch. So I won without using the ball on the middle nor anything on the back side where the zapper and vehicle was on the stone platform. Not sure if that whole section is a red herring or not. I also didn't use any tricks.
I also have won without using the motor draggable or the zap draggable. I just waited for the sequence of Rbot moves to form the desired pattern and used P to block Z. Then herded P round to the R-only ball. Used B to nudge P back to freedom. The only tricky bit was preventing B on P turning right coming down the steps. A prolonged hold on the draggable did the trick.
@RZK Thanks for playing. Forgot how this game played out since it's been so long, but you did exactly what I had designed the gameplay would be.
