I have played both the amiga and PC version (i OWNED the pc version wiht box, manual, map and disks about 10 years ago, i hear its worth alot of money in germany now
the amiga version (i am running right now im WinUAE) has better sound, music, is slightly harder, and mythril the mystic actually does something.
the pc version is a bit easier, but the lairs have more monsters.
the buttons, for all those out there, are as follows
'FIRE (enter)' plus:
up arrow -Strong overhead chop, does most damage but its slow
forward arrow(towards opponent) - quick slash, fast and medium power. good for finishing guys off
Down arrow - This will parry an overhead chop from the other knights and the
axe/hammer guys and the jab from spears (not the big blue trolls though)
back arrow(away from opponent)- reverse chop, weak but sometimes useful
up+forward - upper thrust. good for dragon and balloks (big jumping guys in NE section)
Down+forward - Jab. longest range attack, use on spear men. second spearman wont come until the bleeding stops
down+back - Block. Blocks the Slash of other knights and of the hammer/axe
trollocks.
back+ up - Dagger throw. great to stop enemies and finish guys off.
specials - press down and fire on the ratmen (in forest) to stab them in the head/in the tree. also down and fire when the mudmen have you in their hand.
