Not sure if it's just me, but I can't get this game to run on Mac, even with the Mac download every time I try, I simply get the error message:
The application “Dead_Days_(Mac)” can’t be opened.
I know that sometimes Apple blocks unidentified developers, then you can just go into settings and "open anyway" but I check privacy and Security settings and there was no application being blocked, it simply could not run. Probably something worth looking into.
