Thrallbound

It was a number of years ago I played this public domain Amiga game. It seemed to me more of an exercise by the programmer in what he could do. Overall it only gave the very smallest smattering of Norse atmosphere within a very squarely mapped world map. One item I recall which was required for completion of the game was in an unforgivable location (Spoiler - click to show)you had to dive into the water and find the only location which didn't kill you instantly as I recall . That annoyingly cryptic difficulty was the only thing memorable about the game.
