A lot of people publish Inform games without a walkthrough and without an in-game hint system, which makes those games hard to finish for people who aren’t that good at puzzles, or if the puzzles are harder (or more unfair) than the author realizes.
My favorite approach is to write an in-game hint system that dynamically detects which hints to give you, giving progressively stronger clues until you figure it out, but I recognize that this requires a lot of work.
But you know what isn’t a lot of work? Providing the source code of your game so players can search through it.
I recently got stuck on a game I encountered on IFDB that included its Inform source code. When I found myself unable to continue, I found that using Cmd-F to search the file for keywords was itself a pleasant albeit spoileriffic experience, at least as good if not substantially better than reading a turn-by-turn walkthrough.
I’d still prefer an in-game hint system, but if you can’t bring yourself to write a walkthrough, publishing source may be a nice alternative.
Just a thought!
