I like the idea, and the little ghost guys.
I do agree with Fridgeasaur that it's a little odd being able to move all my pieces in one turn along with all of them getting 3 actions per turn, maybe you could have a limited amount of actions per turn somewhat similar to X-Com?
Additionally I think the ghosts on each side need to have clear distinction on their models, whether through colour or shape, I had multiple instances of clicking on one of my dudes and not knowing if the ghosts surrounding me were friend or foe without clicking back off of my guy.
I hope to see this one polished up to the original vision :D
