I had some thoughts about themes of responsibility, cruelty and past trauma in several of the games I’ve played in this IF Competition. It’s impossible to get too far into that without discussing themes and endgames, so you should be warned of major spoilers for the following pieces:
The Mouse, Norbez
To the Wolves, E. K. White
Rite of Passage, Arno von Borries (be advised that some playthroughs include description of sexual assault)
Hill Ridge Lost and Found, Jeremy Pflasterer
Sigil Reader (Field), verityvirtue
Emily Short's Interactive Storytelling
