Help me put this vampire to bed

I have made a pseudo trained version of Vampire's Empire in the hope someone out there can figure out what to do to finish it. I've shone the light and shot garlic on almost everything and keep winding up at a dead end. Trained version has infinite blood supply and garlic, increased delay on trapdoors opening.. HELP key toggles a mode whereby you snatch the light no matter where it is and the keypad arrow keys move the doctor, defying gravity and obstacles. No strict checking though so if you overdo this expect to run off the map with undefined results.The back box scans of this game show a sort of orange serpent emerging from the thing that resembles a Star Wars jawa. Also bats flying around. Unable to coax either of these out.
Tip if trouble:
unzip vampemp.zip then delete it. add .zip to extracted file and unzip again. You now have the adf and doc file.

I remembered trying to beat this game forever back in my youth. This must be one of the most frustrating games for me. Funny, I don't even remember seeing the title screen on the version that I had before. To be honest, not sure when I'll be motivated enough to try this again.
