Bought the game during the weekly Humble Bundle thingie. "Hey", I thought, "all the episodes! The first episode worked perfectly on iOS, I bet it will work great on my Mac too!". Well, no such luck.
During pretty much all the loading sequences, the game freezes for 10-20 seconds. Music and sounds can still be heard during this time. Additionally, the game crashed during the first loading sequence when I had changed all the graphics options to low / off, as to reduce any strain on the computer that might be causing the problem.
I am running the game via Steam on a mid 2012 Macbook Pro running Mac OS X 10.8.4. I am including the support tool zip file.
