Level three quite difficult – Fireboy and Watergirl Online 2 Review

I beat this game all the time when I was about 8 years old and I expected it to be the same fun, but bearable game. However on this game level three is proving to be very difficult as once I have progressed to a point where I should be able to jump onto the final platform, I can never get either of them to do it. There are no other levers or switches to turn and if someone could please comment the solution to this level I would appreciate that very much.
Review by brawl is super dumb on Fireboy and Watergirl Online 2.
