Sometimes I just want to play a straightforward top-down shooter, just like this. Games don't all have to be super-clever indie avant-garde masterpieces.
Nice job with the movement and the ejected bullet casings, and the lighting.
The theme was a bit of a stretch, but who am I to say that you can't shoot ghosts with holy rounds? I saw the markings on the casings. Makes perfect sense.
Good job.
