Does pressing on quit work? But to save just press save in the pause menu and quit the game through Windows if quit doesn't take you back to the main menu. To bring up the pause menu press P if you didn't remap any controls because that's the default.
Aha, I didn't know how to even pause! My fault for not checking the controls before jumping in. Thanks for answering my question, I really can't wait to get into this game more! It looks beautiful! Oh, also wanted to ask, those animal growls and howls and whatnot, I thought it meant there was actually an animal really close by - sometimes it sounds right on top of me. But I've yet to see anything. I am supposed to be careful when I hear that, right?
