Silly little game where you run from Yanderedev.
It's funny but really forgetable, I play these RPG Maker games for the story (or the atmosphere, like Yume Nikki) but the plot in this one is almost nonexistent, like, yeah, there's this monster killing people in the mansion but that's kind of it, you know? Also I don't even remember the characters names.
I can see how this game is influential to the genre but it really hasn't aged well.
