On Stage 5, which I'm assuming is the last stage, I ended up getting to the area where you take the teleporter/elevators. I can't find out how to progress past this part.
I looked at a guide on Gamefaqs and the only guide there said the person has never finish level 5 either. I usually don't look at strategy guides because I actually dislike them, but I've ran around that stage for about an hour straight attempting to get past that same point and that's the only area I can't get past. I haven't died at the part, it's just not being able to find out how to get past it.
