I tried to play but it's crashing right after the second screen :( I pasted the crash log here: https://gist.github.com/stepheng/4707ec647fd3a71dd...
I changed the font (edited style.default.font = "Zapfino.ttf", in game/options.rpy) to point at a font on my system and I didn't encounter any other issues.
I like the art choice, picking single elements, rather than depicting the whole scene fits well with the narrator's obsession. I also like that the choices lead back to the same point which, again, fits with his madness and lends a pleasing sense of inevitability to the affair. If anything, it would have been nice to see it used more heavily to drag out the ending.
