experimenting with BG implementations
still  Experimenting with some success now,
working parallax background, with graphics somewhat indicative of what i'm intending
added health pick up prefabs, resolved the gibs collision interfering with the chaser.

Locked the firing direction upwards for now, as the delay on being able to aim in a direction due to it being based on velocity makes it incredibly hard to hit stuff. It would need to be based on input direction instead.
