Now I'm trying #64 and have issues with saw: not sure how and when run/jump/slide to maintain necessary speed for inline jump.
Will appreciate any text or picture advice!
Try searching for inline, in-line, joker, April, edge, + saw jump. You should find more help than I can give you on this jump. But basically some door positions set you up for it, and when it doesn't, you have to align yourself using a wall jump off on an opposite wall and that spot can vary depending on where your saw is. Good luck.
