Get it here.
Ok, windows users already got this update more than a month ago, but now all our OS X friends and dads can play the two extra basement levels too. As an added bonus I fixed some rendering bugs that made the game wonky looking on OS X Lion. Octodad now supports OS X 10.5.8 – 10.7+. We don’t have a lot of Macs to test on so if you have any issues be sure to email devon at octodadgame.com.
