I was having the same issue, but through some trial and error I got it working. I'm on Mac, so this may or may not work if you're on PC. I got the game running by downloading the itch app and installing the game through there. Upon trying to launch it, the app gave an error message and couldn't open the game, so I clicked on "see in Finder" and went into the game files and ran the executable file called "nwjs." For some reason, that seems to have worked. I hope this helps!! If you're on PC, you could try the Steam version -- it's Windows-only for some reason, but maybe it works better?
