There's no need for the ball and budgeable, B can simply autopilot from the lift at which he blocks P. Intended solution is nice.
Welcome to the forum - I assume tricks are required in your 1st level? Edit - Please advise? I've won your level with 2 tricks. It would have been nice to know that you were coming with trick requirements for the the intended solution as we don't like to use tricks to win unless we know you know tricks but I couldn't see another way.
I just noticed that your level is in 'Bug/Exploits' area so tricks were intended. The level was nice and I believe my 1st win was as intended but @Block builder is correct ref the mechanism and ball. At this point, you can delete this level and fix the shortcut so the mech and ball are required. Doing so, may give you a better rating.
@Block builder is right but I think that to be your first level is a very promising level...uuuhhmmn,so tricky...Thanks for sharing @Vgbao1231
