Thanks for your feedback!
I personally can't take credit for the art (my friend designed everything ^^). The gameplay was one of my responsibilities and I agree that it has major problems, the balancing being one of them. The ghosts not spawning after dying once, is definetly a bug which I'll fix (eventually) ;)
All in all, I've been thinking about ways to remake the game with a new concept, to replace the "find 3 objects on the map" part of the game play with something better suited for the story and setting of the game. Just having trouble coming up with something atm.
