I thought the ghost models were cute. The game was a neat experience in a surreal environment. After I beat the game, I walked around in it a little longer. I only had a couple bugs where it seemed like the humans floating behind me got stuck in some walls, but I'm not 100% sure they were stuck. The game made me think of Hexen/Doom/40 Winks. It could be expanded further, maybe by allowing character upgrades in jumping, speed.
