Updated with Mac OS version

Hi everyone, Leaf here.

When we first uploaded the game just in the nick of time for the game jam, only uploaded a Windows-compatible version and labeled it compatible with Linux and Mac OS as well. That was our mistake, since we misunderstood what Unity meant by being able to export to all those platforms. We've now uploaded the Mac version properly so none of you Apple kids miss out! If possible, we'll also have the Linux build up soon.
