I got stuck on the level where you crawl through the vents after picking up the first aid syringe and a lead pipe, i kept failing to pass the two giant saws, got any suggestions, or anything you can do to help me out?
You should move about 1/3 through the saw pit and then switch lanes. This will allow you to get to other side. The video on this page shows me doing it if you are still unsure.
You can also level skip back up to where you were with the F2 key btw.
