No, don't worry! I play psychological "cute in the beginning, terrifying at the end"-type horror games all the time; but I'm a huge empath so it just ruins me every time lol
I've already got that ending twice now; luckily no tears this time, but more fear than anything- That end picture has a WAYY different vibe, and Ryuk's eyes in the mirror scared me so bad 😭🤣
And the same goes for you! Don't push yourself any father than what you can take. You gotta watch yourself with these types of games, even if you can handle it, and take breaks between each playthrough.
