Rastan Saga 2 is the sequel to Rastan, containing the same hack-em'/slash-'em gameplay as the original. You are a warrior who must get through a number of levels, and trying to collect gems which can only be obtained by defeating the end-of-level bosses. Collecting power-ups along the way awards you with extra life or better weapons.
Great music, cool first boss, I'll give it a proper playthrough on MAME when I get to 1989. I expect better for the jump responsiveness tho. I get the feeling they were more concerned about full body sprites ha
