Ozymandias walks in a series of interconnected flick-screens, moving in all 8 possible directions. He can jump and duck in order to avoid several minions such as flying bats and harpies. You have five lives to start with and energy can decrease easily when contacting an enemy. Your powers vary from floating up to higher grounds to throwing fire-balls and night visioning (used in dark rooms). All three power can be accessed and activated via your inventory (one at a time though).
Ok the game does not offer any unique gameplay here. Astaroth offers a simple search n collect gameplay which is marginally spiced up by the addition of progressive mind powers. But ok, is playable enough, even for a short time. Not that back to the days, a lot of people bought this game only for its... cover box! Overall, a fairly frustrating game to play, but redeems itself in my ... ears by the superb music.
Ok, technically the Atari ST is almost identical to the Amiga version in terms of graphics. Graphics are well detailed and colored (up to 36 colors on screen here) though it's hard to see the difference between background and objects you can pick up. There are colorful mosaics and statues in the background walls. Sprites move fairly well without any glitch too. Note that all screens are in flip-screen mode so the whole game lacks any scrolling.
Sound is great here featuring sounds FX along with the wonderful music written by Jochen Hippel (note that the Amiga version does not have SFX but... offers this great tune in much higher quality as expected).
