I can definitely see the obstacles change from run to run even today on episode 1, stage 1. I think this is mostly to give beginners a feel for the different obstacles. In most of the later stages they stay the same (you're supposed to run on muscle memory or have the jellies guide you), so it doesn't make sense to randomize them.
