Fragile Shells is an escape-the-room IF game written for Jay Is Games's Escape competition. (Yes, I'm mentioning it months after the fact. It still deserves the attention.)
Like many another escape game, it has a single room full of objects to manipulate before you get to get away: codes, batteries, light sources, things that have to be used on other things. Unlike most, though, Fragile Shells has a coherent story and an effective setting: you're the lone survivor in a very damaged space module, and you need to get into the escape pod before your oxygen runs out or your environment otherwise betrays you. The writing makes it clear just how urgent that problem is, without the need for annoying or unfair time limits on the gameplay.
As you play, you reconstruct what must be going on outside your capsule, filling in the larger emotional context for your struggle.
The puzzles themselves are fair, solid, and well-clued, but what made the game really shine for me was the exactness and plausibility of its imagined setting. Granade is a physicist, and also a gifted teacher. Both qualities come through here. Clear descriptions make the interactions accessible even though you-the-player may not have as extensive a technical background as the character you're playing.
Without being especially profound, Fragile Shells is fun and satisfying, and the sense of place has stayed with me.
