The thing is, David starts sliding when he lands at a higher-than-average speed. At this point, when he's sliding, you need to hold down the down key to make him slide longer. I apologize for the rather awkward tutorial in this level.
did you ever get past this because i tried myself for like 10+ minutes and was just completely unable to find a good middle ground between being slow enough to not fly straight into the saws and being fast enough to still duck
