DOS Games Discussion

i cant remember the name to an old game i believe was DOS. you were a vampire and it was a side scrolling game. you had to beat the level before the sun rose and i believe you could turn into a bat for a couple seconds.
if anyone can remember the name of this game please help
Thanks

I found something through google called 'Vampire Bat'. Google showed an 'official page' for it but I couldn't get to it. Nothing else seemed to turn up. Here's the link that wouldn't work for me...www.gironet.nl/home/awbekker/vbatmain.htm
