The Mac or OSX version of the second release, a vast improvement over the first. Conquer the maze, if you can. Stay alert and watch your back!
Unzip the file and run the application.
Any remotely modern Mac should run the game without issue, excluding MacBook Airs (and possibly any Mac running on an intel graphics chip), which have a known, major graphical issue. This appears to be caused by a combination of strange shader requirements and Unity's custom shader compiler, which we may be able to resolve in the future if there is demand for it.
After performing some testing, the issue for MacBook Airs is confirmed as fixed. However, there is now a lighting issue for all mac systems running with Intel graphics (and possibly Nvidia graphics as well). This is not nearly as severe as the previous issue, but it is still present and does significantly reduce the graphical fidelity of the game.
