My apology for mac users we still can't sort it out, we don't have a mac for steam on site to test, (getting it at this point is not financially possible.) We have gathered more testers to test on steam client but different bugs come with different users. Getting them all sorted at this point is.... not likely until much later in time. (while playing the game directly on mac is fine)
As PC ver is released on steam today and I am currently working on getting steam key to our backers.
We are also in process of releasing the artbook digitally, and ordered the final copies for the higher tier backers. Here's a preview of the physical artbook: www.kickstarter.com/projects/m…
Anyway, I hope that your game reaches its target audience.
