Ok I finally figured it out. For some reason I had to take my finder of the forward key and hit it again to stick.
But....now I'm stuck somewhere else and want to make sure it's not something similar:
When I get to the top of the wall with the metal swing poles interspersed with the fire jets, I don't know what to do. I try and jump to the netting on the left, but I keep falling. When I jump on the rock to the left and jump to a few more it doesn't seem to get me anywhere. Is this another case of having to time the jump to the net correctly? Thanks.
