i'll start. mine is one key: hold to keep a candle lit at a dark window so a stranger walking past looks up. if the flame dies, they don't look. that's the whole game. no tutorial, 20 seconds, and the ending is a note sliding under the door.
it's called Someone Notices and it's my first jam entry: https://candlewindow.itch.io/someone-notices
what's the one action in yours? curious what people do with this little time.
