Nice shots !
Answer to your question in PAL.TOS is that ....well nevermind

Don't ask why, but what and how !
I, for a GFA basic user would say that effects are great, but your screens are lame (flame war muhahahahahaha )
Never went into STOS but, it's some shell for ASM routines, so your screens should be better for sure
For me, as i didn't know asm, i went into STE which proved to enable GFA basic to achieve quite cool stuff (easily confering to pouet comments)

Maybe you could give it a go (STE), and do even better

I bet you have the ATARI ST love, that's so great, go on, keep on , procrastinate the rest

1991 screens aren't things to beat, beat this one :
