Halls of Stonehenge, Level 17

Gol-dangit, this is one tricky level, those flying demons seem to be waiting for me, so's they can pop out
and reduce my health. Very Very annoying. So.....any help appreciated. I got the two secrets before the
door and corridor you have to go through, then around to get to Draven, and he sure isn't a pushover either
Sometimes I have to rage-quit the level and go play something else..
