Since some user had issues starting the browser version, I just added downloadable builds for Windows/OSX/Linux. They’re identical to the browser version, and no updates/changes were made (I will take a day by the end of June to do that).
Actually, the browser version works a little better, because some of the other builds have random graphic glitches appearing here and there. So if you can choose, I recommend playing the browser one.

Salud!
