This is my first serious custom sprite. It's a star sprite which flies up and stops at a certain position which you can easily set in the ASM file.
You could for example let it spawn out from a block, like with these.
The graphics work with the default palette A but be sure to give credit to BlackSquirrel for those.
I tried to document the ASM file as good as I could so there shouldn't be too much troubles by customizing it a bit. Here is a small demonstration of this sprite. No credit needed, just have fun with it. GFX goes in SP4
