(This is an edited version of a review I originally wrote for my blog during IFComp 2015.)
The Insect Massacre is a Twine hyperlinks game about which it's possible to expose little more than the blurb if one is to avoid specific spoilerdom. That blurb is:
"A short murder mystery set aboard a space station."
The title is explained in a neat way which I will also not explain here. This review will be incredibly coy by my standards.
I found the game's mystery intriguing. The events of the story are concrete enough to provoke speculation, but blurry enough around the edges so as to ward off absolute explanation. Multiple plays are required to investigate multiple angles. Each session requires little time.
The game's aesthetic delivery was beguiling on the first playthrough, if a bit confusing in terms of indicating who was speaking in each scene. The speech is effected with colour-coded names matched to coloured lines of text. My proper gripe is that on the second and subsequent plays, the unskippable Twine delays, pauses and fade-ins that were enforced on material I'd already read felt pointless and tedious. Text is basically not a temporal delivery vehicle like music or film, especially text in a branching story.
Fortunately, The Insect Massacre is short enough that even on replays it isn't too hurt by its eternally slowly-fading-in text. It is particularly good at making the player guess at the implications of the choices it presents, and not because the choices are at all vague, but because of carefully deployed elements of the game once again not discussed in this coy review.
