Looks fun. For OS, it just says "11" — does it run ok on Mac OS?
I tested it on Windows 11 and Linux (via proton). I'm afraid I can't say anything about Mac OS until I get my hands on apple hardware and I'm not familiar enough with their emulation layers to take a guess.
I have support for linux, controllers, steam deck, mac on my to-do list in that order - it's simply a matter of time (up-front, maintenance, testing) and money since macs do tend to cost quite a bit. I'm a linux user myself and I hope I'll port it properly sooner rather than later but meanwhile I also know it seems to just work with proton.
