I played it as intended (tho a random shortcut is possible by throwing the cart and letting B fall to the ground and do a boogie bot bug to the win). My biggest concern is controlling the rotor. It can be solved by changing the metal block beside the rotor with a rail or just remove the metal block beside the rotor.
Good looking level with a good start to watch. Did not see the use of the not too obvious central draggable. All it does is stop the second vehicle from moving too far.
Easy but FUN level with cool mechanism...I didn't have any problem with the mech & solved on my first attempt...Thanks for sharing @Electro wolf
Fun ride, but I had big problems with the launch mech for the second cart. It kept flinging B into white space!
