Very nice art style and idea, but I think that in the scary final parts there is far too much dialogue and lack of subtlety; I especially didn't like the demon taunting Kat in what I feel are very cliché sentences: he feels like a cartoon villain explaining in detail what he will do, more than a monster, and his threats ruined the anxiety of being trapped. Also Kat commenting everything didn't allow me to seemlessly put myself in her shoes: most of the time she felt like the annoying friend who comments over a movie more than an enrichment of the plot.
Overall: very good presentation, polished gameplay, entertaining plot and nice atmosphere, but not really as creepy/scary as it tries to be for the issues I talked about.
