Thank you for your kind comment!
If it can help future players who will read the comments, in general, I would advice to avoid to adopt "use" altogether in the game, to prefer more specific actions. One can complete the game using verbs such as take, tie, jump, talk, wear, read, examine, throw, put, give, drive, try, break, pour, turn, touch, plus the common directions, etc...
Sometimes, "use" is recognized as a synonym of a more specific action, sometimes it doesn't.
Cheers,

P.S. if you finished the game, write me privately (there is an email on my blog) with the final password, I'll add your name to the hall of fame on my blog.
