I updated the Mac build to hopefully fix some errors some people are experiencing (IE ground disappearing). I've yet to replicate these errors on my machine so it is hard to debug. Thank you to everyone on the forum trying to help me nail down this annoying bug.
YOU MIGHT NEED TO REINSTALL the game to get it to run properly. If it updates and you can run it great but if not do this. [This will not erase any progress you made] In your game list right-click 'The Superfluous' and select uninstall. Then reinstall. Play.
The good thing about this is it should run with less lag on old Macs.
