Spellbreaker is a much larger puzzle (by sheer number of rooms) than the previous two games in the trilogy. However, there are many rooms which are basically a description and a container of a single object. I felt the spareness in these rooms and several of the interactions with characters. I presume there just wasn't space in the original file formats. This game would benefit greatly from a filling out of all of the innovative ideas in the game.
The theme is compelling, some of the puzzles are appropriate tricky, but the final brief concluding paragraph along with the spareness made this game feel very thin. It's an important game for its time but fails to entertain as much as it could.
