Outstanding, expertly-honed gameplay - equal to the C-64 what GAIARES was to the Mega Drive.  *Just* hard enough to keep you coming back.  Astonishing parallax scrolling, bosses which increase gradually in difficulty, whopping amount of levels. We could only have dreamt of having a SHMUP this wonderful back in the C-64's original hour - for the gameplay and C-64 graphics alone, this is a bargain at double or triple the asking price.
