Wow - This level is so close to the one you posted 3 days ago. The same 1 second move is required at the start if you want to win with B and you still need to drag the FREE DRAGGABLE the same route up. Not impressed. If you are not going to take recommendation or suggestions, I'll stop commenting.
es que esa es la forma correcta, sin embargo estaban colocando el FREE DRAGGABLE en la base final y no usaban el B, por eso tuve que encerrarlo. -- that's the correct way, however they were placing the FREE DRAGGABLE in the final base and they were not using the B, so I had to lock it up.
