Hello, I guess my first question is, is this the first version of the game that you have tried to play? Or did previous versions work and now 0.2.5 isn’t working? Aside from that I’m not extremely versed with MacOS. I know that Mac doesn’t like to give the game permissions so you may want to check and make sure you OS isn’t blocking it.
Other than that the only thing I’ve seen is occasionally there is seems to be an issue with NWjs (the shell that the game uses) where it gets stuck and you have to force close it before you can try running it again. On Windows you would do this with task manager and close any application with “nwjs” in the title. I don’t know what the Mac equivalent to that is but you may try that. Or I suppose you could restart your computer since that would shut everything down.
