Hey Kenney, have you had any time on this recently? I assume as you're building the new version in HTML, it should run on/port to Mac easily too? Apart from Steam, there really isn't any game launcher for Mac as simple and good looking as this!
Yeah the HTML version is still in production although I didn't have a lot of time to work on it recently. It'll come with an OSX version out of the box, but it's plain and simple HTML (with a bit of Node.js) so it should be easy to port to any platform.
