To be fair, the earliest text adventures are brutally, brutally difficult and in many cases, very much unfair! There are nowhere near enough in-game indicators or foreshadowing of what might work in a certain context. Some solutions are obvious, but others are truly ridiculous and won’t realistically be solved without a walkthrough or “invisi-clue” book. All imo, of course.
Back in the 80’s we used to play these games in a group, with one person driving and a group of others helping out. Even then we used to fall back on hints occasionally.
