Fantastic ZX Spectrum dungeon crawler. You are the warrior Hakkenkast, exploring 4 dungeons looking for lost spellbooks. There are monsters to fight, traps to avoid, spells to cast, swords to swing, secrets to find. 128K version has TWO tunes to listen to, and you can swap them. Cracking level design has mazes to explore or to map.

3 lives then you die. But you can continue, losing a level and some gold. 4 dungeons, each are separately loadable games (so you can start at the last one if you want) but you can carry your progress forward by use of a 5 character code.

Fantastic fun! (I received a free copy of the game, but the above is what I think).
