Due to issues with the Mac and Linux versions, they have been removed, and are no longer supported. In place of them is a browser version of the game! It doesn't run nearly as well. It has load times and the audio frequently delays. However, for users not on windows, it was my only option to getting the game to you guys in a working state. If you are on Windows, I would advise against playing the browser version, and downloading the Windows version. It is 100x better and smoother. The browser version is intended ONLY for those without any other choice!
