Nah, it's just a very similar concept. If it's something you're set on creating, go for it. Explaining you didn't know about that game(which is a rather old game) should be enough to ward off anyone claiming you stole ideas.
You said there'll only be direct combat against heroes, so how will the game in general play out? Something like an RTS, maybe, with the minions?
I'd also suggest getting matching sprites, as what I imagine is the dark lord's sprite doesn't match up with the face.
Yes, because you change forms when you get more evil
