It was one of the first DOS games I’d seen, as someone had installed it on the computers at my school. I was quite amazed by it at the time:
– it was a very smooth 3d game with fancy textures and realistic looking monsters.
– controls felt very responsive, and it was enjoyable “dancing” with the monsters, trying to hit them while avoiding being hit.
– the game was simple to understand, so you could pick it up very easily.
– dividing the game into levels was good idea, as it made each level a small challenge in it’s own right, with a well defined goal.
