That was really good! Had my full attention there! The slow building worry of the kid was much more effective than a lot of horror games that just go all out gore and knives. The main talk image of the girl is also really good, that's art goals there.
Did you just display the talking sprite with the show picture function in RPG maker? I'm trying to make my own little game, and have found it to be really cumbersome for displaying images like that. Did you just power through and make it work, or did you use something else?
I was so engrossed by the game that I was really surprised when it just ended. This one is going to stick in my mind for a while.
