So how do you score in a shoot-em-up where you can't actually shoot? There are a few possible ways that come to mind:
- Score bullets: Fired from spawners like normal bullets, but instead of hurting you when you collide with them they give you score
- Bullet grazing: Score points by flying very close to bullets but not close enough to be killed
- Score zones: Marked areas of the screen that award you points when you fly over them
To start with, I'm going to implement..
