I can't create a save file, I've tried all the controls (I'm using a MacBook with the pad thing), but I can't save my game. So I have to redo everything when I leave. The heck am I missing?

Same issue here.

ALSO! Sorry for the constant questions, just keep thinking of new ones after sending the previous message.
When going into the settings to alter sounds or options, the game crashes upon trying to leave.
