Following your comments and other ppl ideas i have changed the game a bit:
* Ghosts now cannot be killed
* Skeleton kill = 100 points
* New maps added and some remade (now harder)
* Vampire spell now has some lifetime until it disappear
* Z to shoot now can be hold to fire fire fire fire :)
I'm currently working on new projects but one of this is a new platform based on this platform engine..
feel free to help me improve my games commenting it and suggesting new features!! :-)
