I made the same exhausted sounds while I translated all the game, it helped me feel the fatigue that the protagonist has. It's simple, but relatable, made me happy when I saw the character more motivated as their house was more clean <3
Also, I felt a bit anxious when people sent me new messages, same happens to me in real life because of my social anxiety lol.
Btw, I'm surprised they managed to clean big areas in one day, I just can't- Also didn't understand if whenever they went to sleep past to the next day, but if not, it's also too realistic, I go to bed every time I do something that may seem minimal too.
