Oh yes, it is far more than a ghost shooter. You should put more emphazis on the "decided to push the ghost shooter to its limits" part and put some screenshots.
Now a little bit of feedback/drawbacks:
* W,A,S,D (fixed) is a combination for qwerty keyboards. Yet my keyboard is an azerty, so I must go left with 'Q' for you, go down with 'Z' while s and d keep their regular use. Strange pattern isn't it ? I'm used to have the middle finger on 'W' for you and go forward. WASD fixed forces me to have the forward key, the lower on the keyboard. My brain freezes ^^
* My screen resolution is 1920X1200. Your 640X480 looks really cute, but I'd like some option to, at least, double its size, or go full screen.
* After the death screen, the mouse cursor stays invisible. (back to the menu).
It should appear until we clicked on New game or something else.
Nice ambiance though, and a good use of CC's effects.
As pixel said, it's more than a ghost shooter.
