Last weekend I was part of a team that made a game called And Then You Die at the London site of Global Game Jam 2014. It's a comical and surreal story builder game and we had a lot of fun making it Also it has a nice dynamic soundtrack which changes based on player choices. There's a browser version and also desktop downloads which you can find here: http://globalgamejam.org/2014/games/and-then-you-die Have a go!
Yeah the first time you play it will take a minute to load after pressing play. Seems like it depends on the browser though?
