received from Mariano Domínguez Molina from Mexico:
Hi !!!
I've played Wlokczij in my NTSC machine and works good ... except that
tha winged-fishes appeaar sometimes like "ghosts" in the screen, i.e
each one of these foes appear double in the screen: the "real" thing and
a "blinky" foe, this makes the game really difficult.
