Not good enough, those polearm knight attack so fast it's hard to counter attack them. btw, u just have to go through a lot trial and error to know where to go. What do you mean? It's youtube.
Challenge 6 video uploaded. It's one of my favorite stage. You get to feel the speed!! 3 attempts failed before the 4th one succeed. Some jump is hard to achieve, you must have near perfect timing. 4th attemp starts on 2:30
