The game was originally created in Unity 5.5.3 but this meant the game was not supported on current versions  of Mac Os. I've updated my Unity version and shabobble now supports MacOs Catalina. The code handling the physics of the game had to be reworked a bit to cope with the updated version of Unity, but it's as close to the original as possible. There are some minor differences in the physics of the windows&linux version vs the mac version but they're too minor to be notable.
