For Mac users:
I bought this game as the demo was cool! -- The paid version uses DirectX 12 , thereby making use on a Mac with a Windows VM useless. Sad as the features of DirectX 12 are certainly not needed for this game. Simply a developers choice.
The developer never claims Mac compatibility. If you're intent is to run on Windows via a VM, (Virtual Box, VMware Fusion) then I'd recommend you hold off purchase. Demo works just fine. We'll see if NoxDev has more insights. Probably not worth their time to rearchitect for DirectX 11 or earlier.
