The bouncing effect on saws hasn't really been reduced. On the level where there is a huge hill with archers on the side and sword enemies coming to slice you to bits, I can run and jump on top of a saw blade a fling into the air as if I could fly. I'm pretty sure this is just a little quirk on that particular level, because in other levels I just get shredded to scrap metal.
I can't seem to reproduce any abnormal hopping on the SpidertronNest levels. Is there any way you might be able to make a video of this happening? It might give me a better idea of what's going on, and whether or not it's a bug.
I can try to record whenever I am on the level, but it might be hard to have it happen, as it is completely random. So far it has only happened 2 or 3 times over the course of about 4 hours of game play, so I might be hard to reproduce the event.
