I like that moment in manga, when Armin scares everyone and Eren just “no, actually he’s always like that”.
I experienced other games of this kind: children as protagonists in a creepy atmosphere. But I think Sally Face is even better than Fran Bow, Little Nightmares or Undertale. Because it's believable. I grew up in an apartment block, the characters are relatable and ghosts - or restless souls - are a great supernatural addition to Sal's situation. I also hope that your game will become more popular so the fandom will grow. The fanarts I have seen so far were absolutely amazing.
