Interesting how this game combines fantasy stuff like demons/rituals/clairvoyance and grounded problems like cover-up/evidence/body disposal/laying low from cops.

Similarly combining polar opposite moods for events when you kill people, finish off parents and stuff that suddenly turns into a fight between the duo in some lighthearted tone.

You can even consider the contrast between the clean character design and their horrible personalities. Not to mention the contrast between siblings themselves.
