Super hexagon is crushingly difficult, it's the one game I can keep returning to over and over on my commute. Flappy bird also hits a similar spot, it's a game that's quick, each game lasts < 1 minute so you can play right up to the minute your train pulls into the station, and it has the anticipation of defeat in a similar manner.
