This game (I think it was made for Shufflecomp?) really touched me. You play as a person in a kind of melancholy town at evening, watching grass blow and seeing things like power lines swaying in the wind and an old radio. When downloaded, the game plays peaceful, ambient piano music that strongly affects my rating.
Gameplay is about wandering around, at first, and then learning to interact with the world in a new way.
There are some whitespace issues and the interactivity took me a bit to figure out, but the music was polished and I loved discovering the mechanics. Very emotional, very powerful, I can't remember the last time an IF game made me feel this way (but I don't expect all readers to feel this, as it just happened to fit my mood and time of day, and things always feel better when you discover them organically rather than when someone tells you they're cool).
