I like the concept of the game, but hopefully the game will be accessible for the PC I'm using in the future which is a MacOs because I really want to check it out. 

Since it looks quite promising.

You know you can use WINE (Windows Emulator) for MacOS, too, right?
It just might take a bit of space to run Windows-Games, if you don't want to use Apple's "Parallels" to run Windows in a Virtual Machine though.

Just search for "playing Windows Games on MacOS" and you'll be able to learn a lot more of the possibilities of MacOS and Windows Games.
I have an old MacBook still, on which I have installed it and it runs fine for most of the Games - similar to Linux, which I also use - and with a new MacBook you won't even have performance issues on most Games.

Cheers
