It seems that the game cannot be downloaded on my Mac. Has it not been released yet?

Version 0.1.5 Part 2 is only able to be downloaded with 5$ price as of now (it got released 6 days ago). Unfortunely it's also the first build which we started to support Mac version. You can check out Part 1 on PC , which is free now, or wait until the end of this month for Part 2 to become free. Hope this solves your problem!
