I found that if you actually download the itch.io LAUNCHER rather than the game itself, and then run it from the launcher, it seems to work ok. But yeah... the thing just won't really open by itself it seems..
Sorry you guys are having trouble with Mac! There isn't a whole lot we can do, as this is because of how Mac treats Ren'py projects, and we don't have a Mac to test with to try to tamper with the way the app gets bundled. We would if we could!
