-Note- There wasn't much i was able to do with this stage, the thing that i thought made it look okay was the lens flare, but it took almost half of the FPS.
It went from 60 to 48 FPS (on my pc)
So if you want better FPS just remove this code from the .DEF
[BG Flare] type = normal spriteNo = 1,0 layerno = 1 start = 0,-168 delta = 1.5,1.5 trans = addalpha alpha = 170,256
