Overall, I think the idea can be quite addictive, but some balancing might need to be done. For example, the player should go just a little bit faster so there's some chance of outrunning the monsters.
I didn't quite know what to do with the ghosts, I thought that since I'm a ghost, maybe I'm supposed to free/eat them? But nope! :D
