I played this for about an hour (really liked it!), quit, came back, and I have no option to continue my game. I tried putting in the same username I stared my first game with but got a prompt telling me I'd be starting a new save file. Am I being dull? Is this a known issue on OS X?
I quit the game after beginning the 3rd "real" mission, that is, after finishing the mission with Murphy and starting the next mission. I believe I just quit the application rather than "Logging out", but I tried experimenting with starting new games and then Logging Out and I have yet to see an option to load my game. Please help :)
