Okay, I am not too sure about bullet colours. I will probably have sets of different colours for bullets, but that would mean I would have to redo stuff. Currently I have bullets wildly named inside GFX-folder, so I probably want to throw them somewhere else. Like proper folders. And make them into sheets so they will be easier to switch.
I am probably allowing the modifying of game's graphics. But that means I have to rid everything that depends on size of the sprite. Luckily bullets' hitboxes are now sprite-independant.
Behold the colours!
Also, I was fixing boss-code. It was horrible. Now it might be better.
