This is really really cool!!
It's one of the most unique control methods I've seen in a while, and the art is really spooky looking!
My one constructive piece of advice would be, when you click up to kill the enemies, it would be nice if it created the beam attack, even if you weren't lined up below an enemy, as I think it would make killed them just a bit easier.
Otherwise tho, fantastic job super cool and creative game!!
