I don't think this game needs cheats, it's quite easy and you have a lot of tools to make the ghost hunting easier. The game deserves the time to play it and go through it, if you don't have time im sure someone will post a full gallery save or full save when it's done. Just be patient.
Either way the game is not that difficult and you have extensive walkthroughs to help you get through everything plus the discord server where you can ask and check any doubts. It's worth playing it.
