Thank you for the insightful comment! We haven't stopped working om the game, so feel free to check back in next week.
The resolution limit was a challenge in terms of text, so we put the instructions on the game page.
The reason we limited Sokoban retries was adding flavor to the challenge. You don't need a perfect solution to get a clue, and trying to figure the "whodunnit" part with clues of lesser "quality" is part of that zest. I'm glad it made you feel differently about approaching the puzzles, and hope you didn't find it frustrating.
But the clues, suspect info and which suspect is the killer changes each time, so playing it a few times until you figure out the puzzles is always an option. Maybe we could communicate that better going forward.
