too hard. Can't get past the part where you get the speed up power up. I keep thinking I've figured out a strategy to jump between the two blades that are lined up with each other but then it doesn't work. Maybe I'll come back later...
Or maybe if there was a checkpoint directly after the part where you have to jump between the two blades on top of each other? Because sometimes with luck I can make it through but then I'm instantly killed on the next part where you have to jump over two blades that are together. Then it gets frustrating because you have to wait to have good luck again with the first part.
