The thing about game bugs is just because you have no issue, doesn't mean others aren't. I had not issues getting stuck in nets, yet some other people did have the issue. A issue that was game breaking for a lot of people. If you search these forums you will see various posts about bugs from Mac users or Linux users who can't even get the game to open, let alone play it.
If they keep releasing Mac and Linux versions but don't fix the bugs that will inevitably come up, those version will become unplayable after a while and riddled with bugs. It sucks, but when you have a tiny dev team that is doing this game on the side as a hobby (basically), you're asking too much for them to make it perfect for all platforms. Even bigger developers tend to focus on one platform at a time, then release others after the first one is relatively bug free. We're kinda lucky there's any more development happening on this game at all, right now, with the time constraints and real life obligations these people have.
Maybe in the future, they will bring back support for other OS's. In the meantime... there's always Wine...
