Nicely done!
For those unfamiliar with the "language" of 1980s text adventures, you can find the manual for this game at https://www.mocagh.org/tolkien/hobbit-alt2-manual.pdf and the 1984 guide to this game at https://ia801809.us.archive.org/17/items/guide-to-playing-the-hobbit/GuideToPlay...
but do be aware that if you read the guide beyond the first dozen pages, it will start to give you clues or outright answers to the puzzles in the game. Those first dozen pages of the guide should be helpful however, being effectively the "game manual."
