Thank you for taking the time to write us such in-depth feedback.
Some clues that were supposed to increase the difficulty were missing. We're planning to make some updates to make the game slightly more difficult and add what we forgot to include before the jam deadline.
The notes are in a notebook kept by the building's caretaker. It was added so players wouldn't forget anything important and could access extra information they might have missed. We could review it, add more text, and only keep the additional information players actually need to find the culprit.
Your feedback will be really helpful for our future updates. Thank you so much for taking the time to play!
