Guess you cannot expect much from STOS and this is what you get. Looks this the poor ST conversion once sold as a commercial games yet without any enemy here...

Erm I meant "Looks like the poor ST conversion" (guess I was tired when I wrote this).

Three years later and I need to say I am sorry about what I wrote ! The ST commercial game ran much slower than this ! Colours could be a bit better still thumb up for making this run with STOS ! My bad !

awesome shaders!
