Yep. But they don't. And I don't like the fact that they do in Origins.
Oh well, let's go over Rayman 2.
The Marshes of Awakening
A tiny part of The Sanctuary of Water and Ice
About half (?) of The Menhir Hills
I suppose you could also count the plum-riding segments, but I'd disagree with that assessment; you can control the plum perfectly fine, you aren't pushed to go forward
The Precipice, I suppose
About half (?) of The Echoing Caves
Parts of Beneah the Sanctuary of Rock and Lava, I suppose
A tiny part of The Iron Mountains
Most of The Prison Ship
And that's everything I could think of. Still, because Rayman 2 is 3D, these 'speed' levels are much better, and in fact, don't feel as a speed level to me at all. I also wouldn't count plum-riding segments as speed levels, but, I just listed everything I could think of. But then again, I suppose The Canopy and The Tomb of Ancients could also count as speed levels; spiders chase you.
But still, you aren't forced into those speed levels. You can control the plum - you aren't rushing through the level. You can kill the spiders. And also, speed, here, is slower than in Rayman Origins, and three-dimensional. It's less rushed, and, to me, provides a more enjoyable experience. I love The Precipice (I suppose a large part of that is subconsciously because of the music, but I still like the level itself) and the sanctuaries, I don't see them as speed levels.
Rayman Origins is faster, two-dimensional, and has a one-shot-kill system (I just coined this term, but you get what I mean

), and on top of that, about every single level is a speed level. Rayman 2 has less speed parts, they're slower than in Origins, and they become even less speedy because most of the time you have more area to manouver in (three-dimensional) and because it has an actual health system (which, however, doesn't matter in the speed levels of Rayman 2, but because Rayman Origins is a speed 'game', it has much more variables (as in, enemies, stuff that hurts you) that make the game even more fast-paced, that would have less an impact with a health system).
Well, that was a long post, and I mostly repeated what I said previously... Oh well.
