Thank you so much for playing!
If you haven't tried it, you might need to interact with some objects a couple of times before you go to the next day :)
And if you'd like a clue, you can tell me which characters you have already solved!
Yeah, it might not be quite clear now, we are working on the updated version to make the experience better.
Right now there are options to interact with some objects once you've talked to a person. You need to click on their window again and there may be some objects the character can interact with (you'll be able to click on them and get a reaction). The certain objects are interactable at certain days :)
