Compiled on Mac; Game crashes on start!

[Urkle]

Now are you just compiling and running it FROM xcode? As that won't work as the game doesn't have any of the data files..

So the game is most likely NOT crashing but rather quitting because it can not find it's data files. You have to have a purchased copy of penumbra overture and run the binary with those data files in order to run it "as-is". To create your own custom game you'd need to create your own data files.
