Stuck in "Let's Waltz"

[Photonium]

Message for the developers. This game was fun until I got to the Auto Factory in "Let's Waltz". First, I couldn't figure out what to do after jumping onto the ledge above one of the cars. Didn't realize you had to use the circular lamps to move along. Had to look online to find the answer. Then, though I'm playing on Easy, my timing's way off and my stamina runs out to get much much further than the second platform hanging from the ceiling. Given that there are sometimes alternate ways to solve a quest, so far I haven't found one around the Auto Factory. I ran out of ingredients to give myself more stamina. Right now, that means the game's unplayable for me. Is there some secret path I've missed to get further into the factory?
