I liked the concept of catching ghost with lights! Though ghosts are not really harmful to player and the player can just ignore the ghosts and turn up the lights to proceed. I would suggest adding more type of lights and ghosts to make the puzzle element more interesting. Nice work :)

Thanks - yes, I think there is going to be a win condition that all the ghosts have to be gone before you can proceed to the next round, and potentially use the blocks to move them into the right spots. Someone else also suggested restarting the level if you hit any ghosts which I think is a great idea. Lots to implement. Will be busy for a while on this project :)
