Min RAM for this is actually 1 MB - when playing from floppy disk.
Not STE HW scrolling, not blitter. Just good 68000 code. So, same on ST without blitter.
lovely stereo music there.. and don't forget to press F9 during the game for awesome chiptune. Uses STE hardware scrolling (or Blitter?) and it's as smoooooth as silk. Hard game too, very challenging but also enjoyable. Love this game!
