One of the best tricks an IF author can pull off is to make the narrator of the game a central NPC; we saw this, for instance, with Violet, and we see it again with Ugly Chapter. Here, the narrator is utterly filled with resentment against the player character, which leads to --
-- really, saying any more would be spoiling this short piece.
Ugly Chapter is a piece of Speed-IF, and it shows: implementation is sparse, the highly linear path through the game is slightly underclued (but see this walkthrough), and the story and setting, though good, are more hinted at than developed. Still, given the small scale, this is an impressive work.
And it makes me itch to see more pieces where the narrator has a strong emotional investment in what is going on in the game.
