Looking for name of game

Hi,

I played a game a while ago that was kind of like a tower defense game, except you mined our the area, and your character (an overlord or something) walked around trying to avoid the heroines catching him.

You could spend mana casting things like orcs, succubi, hounds, walls of vines and worms, and after each heroine was captured/defeated you could do stuff to them in your dungeon.

I'm pretty sure it was an executable flash game or something.

I know this isn't much to go on, but I cannot remember anything about the name, and it was a couple of years ago.
