Architechts Tomb -- Spinning Blades -- Timed Challenge. Having extreme difficulty in making back across the blades and through the door in time. I can get across w/o having to wait for any blades to pass by so this really isn't a problem. After I depress the switch closest to the door I only have time for 1 roll and shoulder thrust before it closes again. I heard that 30 seconds was the time limit however, it it really is only 22. Any suggestions?
