This game was created over a period of 30 years, using a variety of design systems.
You play a natural philosopher in medieval times, nicknamed Phil. There are a ton of puzzles and a magic system.
However, this game could use some thorough beta testing by six or more people familiar with modern IF conventions. Directions are omitted from room descriptions, puzzles are undervalued, and there's an inventory limit which doesn't really seem to do much in-game.
For people who enjoy struggling with the parser in old school games (I'm in that group, and intend to play this one again!)
